Demonstrators rally against policy brutality in Millennium Park

CHICAGO -- Demonstrators are gathering at Wrigley Square in Millennium Park  for a rally, march and then a sit-in. This comes after the release of the police involved shooting videos of Paul O'Neal on Friday.

A Chicago police officer fatally shot O'Neal July 28. Dash cam and body camera videos show officers firing repeatedly at a stolen Jaguar driven by O'neal -- then officers handcuffing the wounded, unarmed 18-year-old, after a chaotic foot chase through the South Shore neighborhood.

The body camera worn by the officer who fired the fatal shots was not recording.

Protestors with the Black Lives Matter movement, as well as families of individuals killed by police, are taking part in this protest today. They say it is aimed at breaking the divide between communities and bringing youth from all areas of Chicago together -- highlighting what they say is the systemic oppression against people of color.
