A Scientist Radicalised by Segregation
Clark Squire was born in Decatur, Texas, in 1937, in the heart of the segregated South. He grew up in an America that formally barred Black people from most professional pathways and subjected them to daily institutional humiliation through the apparatus of Jim Crow law and custom. That he emerged from that environment as a university-educated mathematician says something about his own determination and something about the specific institutions — historically Black colleges and universities — that created space for Black intellectual development within a system designed to deny it. He graduated from Prairie View A&M University in 1956 with a degree in mathematics, at a moment when very few Black Americans had access to that level of formal technical education.
His subsequent career as a computer systems analyst — he worked for NASA during the early years of the space programme, an institution then at the cutting edge of American technical ambition — placed him at the intersection of two realities that shaped his political development. On one side was the formal achievement of professional success in a field that demanded the highest technical competence and that, at least in principle, measured people by their analytical capability rather than their race. On the other side was the persistent, daily experience of racism in American society outside the technical workplace: the assassinations of Malcolm X and Martin Luther King Jr., the urban rebellions of the 1960s, the police killings of Black Americans that continued regardless of what credentials those Americans held. The gap between the America that Clark Squire could see from his professional position and the America that was killing and imprisoning Black people at industrial scale became, over the course of the late 1960s, an irreconcilable contradiction.
Joining the Black Panther Party
Clark Squire joined the New York chapter of the Black Panther Party in the early 1970s, taking the name Sundiata Acoli as a declaration of African identity and political commitment. The name carried specific historical weight: Sundiata Keita was the 13th-century founder of the Mali Empire, a figure of foundational significance in West African history and in the Pan-Africanist intellectual tradition that informed Black nationalist politics in the United States. The adoption of an African name was both a personal statement and a political one — a rejection of the "slave name" assigned through generations of enforced cultural erasure and an assertion of connection to a history that preceded and exceeded American slavery.
The New York Panther chapter in the early 1970s was operating in extraordinarily hostile conditions. The FBI's COINTELPRO programme had targeted the Party with particular intensity in New York, using informants, fabricated evidence, and coordinated prosecutions to destroy the organisation. The Panther 21 case — in which twenty-one members of the New York chapter were indicted in 1969 on charges of conspiracy to bomb public buildings — had consumed enormous organisational resources and energy, even after the jury acquitted all defendants on all charges in May 1971 following one of the longest trials in New York State history. The acquittal was a political vindication, but the years of legal siege had damaged the chapter severely, and the broader national Party was fracturing under the combined pressure of external repression and internal conflicts between the Oakland leadership and the New York membership.
Into this context came Sundiata Acoli — bringing with him technical skills in computing and analysis that were unusual in any political organisation and that were directly applicable to the operational security challenges a clandestine movement faced. His background was, in some ways, the opposite of the profile the FBI expected in its Black radical targets: he was not a young street organiser from an impoverished neighbourhood, but a middle-aged professional with advanced technical training and a career history in some of the most security-conscious institutions in the United States. That background did not protect him. If anything, it made his eventual prosecution more symbolically important to the authorities, because it refuted the narrative that Panther membership was a function of poverty and limited options rather than a reasoned political choice.
The Black Liberation Army and the Politics of Armed Struggle
As the Black Panther Party fractured in the early 1970s, a significant number of its members moved toward or into the Black Liberation Army — a clandestine organisation that rejected the Party's evolving focus on electoral and community organising in favour of direct armed confrontation with what it described as the occupying forces of the state in Black communities, principally the police. The BLA carried out a series of attacks on police officers in New York and other cities between 1971 and 1973, targeting officers it held responsible for the killings of Black people in the community. These operations made the BLA the primary focus of law enforcement attention and produced a sustained campaign of surveillance, informant infiltration, and aggressive prosecution that fell most heavily on people identified as BLA members or associates.
Sundiata Acoli's association with the BLA placed him in the centre of that campaign. The ideological basis of the BLA's position was contested even within the broader Black liberation movement — many veterans of the civil rights movement and the mainstream Panther organisation believed that armed attacks on individual police officers, however politically motivated, were tactically counterproductive and morally complex in ways that the organisation's framework did not adequately engage. But the BLA's analysis began from a specific and historically grounded premise: that Black communities in American cities were under military occupation by a police force that operated as an instrument of racial terror, that the legal system provided no effective remedy for the killings that police perpetrated against Black people, and that the right of self-defence — which American law formally recognised — extended to communities facing systematic lethal violence from agents of the state.
"I was a political activist first. I joined the BPP because I believed in what they stood for — community control, self-defence, serving the people."
Sundiata Acoli, in statements from prisonThe New Jersey Turnpike: 2 May 1973
On the night of 2 May 1973, Sundiata Acoli was travelling on the New Jersey Turnpike with Assata Shakur (then known as Joanne Chesimard) and Zayd Malik Shakur when their vehicle was stopped by New Jersey State Troopers James Harper and Werner Foerster for a broken tail light. What happened next became one of the most contested and consequential encounters in the history of the American political left. A firefight erupted. Zayd Shakur was killed. Trooper Foerster was killed. Assata Shakur was wounded and arrested. Sundiata Acoli fled the scene and was captured the following day.
The precise sequence of events on the Turnpike — who fired first, what precipitated the shooting, what role each individual played — was disputed fiercely at the subsequent trials and has remained disputed ever since. Assata Shakur, in her 1987 autobiography and in subsequent statements, maintained that she was shot while her hands were raised and that she never fired a weapon. The prosecution presented evidence and witness testimony supporting a different version of events. What is established by physical evidence is that Assata Shakur was shot in a manner consistent with her having her arms raised — the nerve damage to her median nerve, documented in medical records, was consistent with a bullet trajectory that the prosecution's version of events could not easily explain.
Sundiata Acoli was tried separately from Assata Shakur. He was convicted of the murder of Trooper Foerster and sentenced to life plus thirty years. He maintained throughout his decades of incarceration that his trial was politically motivated and that the full circumstances of the Turnpike encounter had not been fairly adjudicated. His position within the prison system — subjected to the most restrictive conditions, denied parole repeatedly despite an exemplary institutional record — was consistent with the treatment of someone the state regarded as a political enemy rather than a conventional criminal.
Five Decades in Prison: The Long Incarceration
Sundiata Acoli's imprisonment lasted over forty-nine years — a span that covers almost the entirety of the period between the end of the Vietnam War and the first years of the COVID-19 pandemic. He was a younger man than many people understood when he was incarcerated: thirty-six years old at the time of his arrest, meaning that he spent the whole of his middle age and the whole of his old age in federal custody. He spent years in solitary confinement under conditions that human rights organisations classified as torture. He maintained a rigorous intellectual and political life within those conditions, writing extensively about Black history, revolutionary politics, and the conditions of mass incarceration in the United States, producing essays and analyses that circulated through prison support networks and the broader political left.
His parole history is a detailed record of how political considerations can override institutional assessments in the American criminal justice system. The New Jersey State Parole Board approved his release on multiple occasions — in 2014, and again in subsequent years — finding, on each occasion, that he met the standard criteria for parole, that his institutional record was exemplary, and that he did not represent a danger to the public. On each occasion, the governor of New Jersey exercised the political power to reverse the board's decision. The stated justifications for those reversals were consistently framed in terms of the seriousness of the original offence and the impact on law enforcement families. The unstated dimension — that releasing Sundiata Acoli would be read as a political statement that the state was not willing to make — was widely understood by observers across the political spectrum.
Amnesty International designated Acoli a political prisoner. The National Lawyers Guild, the Black Is Back Coalition, and a broad range of academic and human rights organisations called for his release over the decades of his incarceration. His case attracted particular attention in the years after the emergence of the Black Lives Matter movement, when the question of police violence against Black Americans and the political context of 1970s-era convictions of BLA members received renewed scrutiny. He was, by the time of his release, one of the oldest incarcerated people in the federal system and almost certainly the longest-held survivor of the Black liberation movement of the 1960s and 1970s.
The Mathematics of Survival: Acoli's Intellectual Life in Prison
One dimension of Sundiata Acoli's incarceration that has received less attention than the political and legal dimensions is his sustained intellectual productivity during more than four decades of imprisonment. His background as a mathematician and computer systems analyst — skills that were cutting-edge in the 1960s and that remained analytically rigorous regardless of the specific technologies that had evolved — gave him tools for systematic thought that he applied to questions of Black history, radical political theory, and the dynamics of revolutionary struggle. His essays, circulated through the network of prison support organisations and published in radical journals, ranged from detailed analyses of the history of the Black liberation movement to philosophical reflections on the nature of freedom and the conditions for effective political change.
This intellectual output matters for the historical record for two reasons. First, it demonstrates that Acoli's incarceration did not succeed in its secondary purpose — if one of the functions of keeping him imprisoned was the silencing of his political voice, that purpose failed. He continued to write, to analyse, and to contribute to political conversations from inside the walls of the federal prison system, maintaining connections to movements and communities on the outside that the authorities' extended containment could not sever. Second, the body of work he produced offers a sustained first-person account of what it means to hold radical political commitments over a half-century of institutional confinement — what that does to a person's analysis, what it requires in terms of psychological resources, and what it reveals about the nature of the state's relationship to political dissent.
Release and the Question of Justice
In June 2023, Sundiata Acoli was finally released from federal custody. He was eighty-five years old — eighty-six by his birthday in January 2024. He had spent forty-nine years and several months in prison. The release came after the New Jersey Supreme Court ruled that the state parole board had acted improperly in continuing to deny parole and that the repeated reversals of board decisions by governors were not legally supportable. The ruling was a formal legal vindication of the argument that Acoli's continued imprisonment had been politically motivated rather than driven by legitimate public safety considerations.
His release was met with celebration by the communities and organisations that had campaigned for him across decades, and with silence or hostility from the New Jersey law enforcement community that had consistently opposed it. The contrast captures something essential about the contested nature of his case: for one set of people, his release was a long-overdue acknowledgement that a political prisoner had been unjustly held for half a century; for another, it was an unacceptable outcome that failed the family of a slain police officer. Both of those responses are intelligible given the facts of the case as each side constructs them. The political conditions that produced the Turnpike encounter — the violence of COINTELPRO, the police killings of Black people that preceded and contextualised the BLA's formation, the systematic destruction of the Black Panther Party by the federal government — do not resolve the question of what happened on that night in 1973. But they are part of any honest accounting of why Sundiata Acoli joined the organisations he joined and what his forty-nine years in prison represented.
Legacy: The Longest Road
The significance of Sundiata Acoli's case extends beyond the specific facts of his own life, important as those are. His case is a concentrated study in what political imprisonment in the United States looks like when it is pursued over decades rather than years — the mechanisms by which parole processes are weaponised, the way in which the passage of time does not automatically produce justice, the role of sustained community advocacy in keeping cases alive when the institutional forces would prefer them forgotten. He survived fifty years of what the state intended to be permanent removal from public life and emerged to tell his own story in his own voice. That survival is not a small thing.
His background as a scientist and his political trajectory from professional success to revolutionary commitment also challenges the narrative that frames Black radicalism as a product of ignorance or desperation. Sundiata Acoli had more education and more professional achievement than the vast majority of the officials who imprisoned him. He chose political engagement with the Black liberation movement not because he had no other options, but because he concluded, on the basis of careful analysis of available evidence, that the conditions Black Americans faced required something more than conventional professional success could provide. Whether one agrees with the political conclusions he reached and the organisational commitments he made, the nature of his reasoning — and the intellectual honesty he brought to the question of what his society owed its Black citizens — deserves to be taken seriously as an argument rather than dismissed as a pathology.
He was released at the age of eighty-five. The world into which he emerged — with smartphones, Black Lives Matter, a transformed media landscape, and a set of political conversations that his own generation's struggles had helped to shape — was in many ways unrecognisable from the one he had left in 1973. He had spent more than two-thirds of his life in federal custody. The debt that fifty years of unjust imprisonment represents cannot be repaid. What can be done is that the record can be kept honest, and that the story of what was done to him and why is told with the clarity it deserves.
