neighborhood felt "watched all the time", calling the police "plantation overseers". These frustrations caused a peaceful rally to turn into an unprompted riot at Irving Park in 1967. After this, the Intelligence Unit collected information on any vocal activists and their friends, then harassed individuals "until they found a charge that would stick". A 1969 class action lawsuit on behalf of 20,000 Black Portlanders led to the 1971 settlement called the Probasco Decree. It required the police to stop using "insulting, degrading or ethnically derogatory terms" towards citizens, banned the use of SAP gloves and leaded batons, and required a search warrant to enter a home. The Internal Affairs Division was created, though it was substantially ineffective, tossing out 90% of complaints in the first year, and nearly 93% of complaints in 1979. Police behavior did not change; in 1974, a resident wrote Mayor Neil Goldschmidt stating "It seems as if any time a police gets the urge to punch something, they snatch the first available black man they see, and use him to satisfy their savage egos." Four Black men were killed by the police in a six-month period of 1974–1975. In March 1981, PPB officers (Craig Ward, Jim Galloway) dropped dead possums in front of Burger Barn, a Black soul food restaurant owned by George Powe on MLK. Witnesses said there were seven officers and four patrol cars involved. Ward and Galloway said they did it to relieve stress, not out of racial motivation. After pressure from the Black United Front and protests, Ward and Galloway were fired, though no other officers were punished. Stan Peters and the PPA protested the firings, organizing a "Cops Have Rights Too" rally, and demanding Charles Jordan, Portland's first Black city councilor and police commissioner. PPA hired Ward and Galloway to work for the union in the meantime; months later, the firing of the two was overturned in binding arbitration, which found Jordan failed to follow procedures. Marches and rallies were held, and Rev. C. T. Vivian came to the city to organize anti-Klan efforts, believing the possums represented a "Klan mentality" in the department and the ruling would lead to further attacks. In 1985, Penny Harrington became Portland's first female chief of police, and the first to head a major U.S. police department. Also in 1985, PPB killed a Black veteran, Lloyd Stevenson, by placing him in a chokehold. Stevenson had
