CHICAGO (AP) — Protesters are planning to gather at a Chicago park where 50 years ago Martin Luther King Jr. called for fair housing.

Their rally is expected to focus on last month's police shooting that killed Paul O'Neal, a black 18-year-old. Nine videos released Friday showed Chicago police firing repeatedly at a stolen car as it careens down the street away from them.

Police Superintendent Eddie Johnson has stripped three of the officers of their police powers after a preliminary investigation concluded they had violated department policy.

Johnson promised Friday that that if the officers acted improperly, they would "be held accountable for their actions."

A memorial was unveiled Friday at Marquette Park, where King held a march on Aug. 5, 1966. A march, festival, speeches and concerts were scheduled for Saturday.
