Parks collaborated with members of the League of Revolutionary Black Workers and the Republic of New Afrika in raising awareness of police abuse during the conflict. She served on a "people's tribunal" on August 30, 1967, investigating the killing of three young men by police during the 1967 Detroit uprising, in what came to be known as the Algiers Motel incident.
At age 81 Parks was robbed and assaulted in her home in central Detroit on August 30, 1994. The assailant, Joseph Skipper, broke down the door but claimed he had chased away an intruder. He requested a reward and when Parks paid him, he demanded more. Parks refused and he attacked her. Hurt and badly shaken, Parks called a friend, who called the police. A neighborhood manhunt led to Skipper's capture and reported beating.
