During Hamm's first week at
Newark Arts High School in the fall of 1967, he witnessed an altercation onstage between the student government president and the principal. The student was dragged away from the podium after repeatedly violating the principal's instructions not to talk about
the war in Vietnam. The experience was among many formative experiences that would inspire Hamm to begin organizing. By the time he was a senior, he organized student protests and
sit-ins, The Student Federation produced a list of 27 demands to the school board, including improvements for school facilities and greater student involvement in decisions that affect their education. Over 400 supporters attended the board meeting in favor of the resolution. He returned to Princeton in 1974. The same year, along with People's Organization for Progress, he organized and led a 12,000-person Newark
George Floyd protest against police brutality, which was also fronted by Newark mayor
Ras Baraka and featured speakers and dance activism.
The New York Times stressed the peaceful aspect of the protest and its successful de-escalation, citing community members' memories of widespread violence during the
1967 Newark riots. Hamm has been vocal about his opposition of
Trumpism and its desire to establish
minority rule. He stated to the
New Jersey Monitor,"
Dr. King said our country, the United States of America, is ‘the greatest purveyor of violence in the world.’ That was true in 1968, and it is true today. Genocide is being carried out before our very eyes. And if the United States government does not use the leverage that it has, we are going to be drawn into another forever war." As chairman of the POP, Hamm organized the Martin Luther King March Of Resistance in Newark on January 18, 2025. The rally and march took place at the
