Thousands of people marched on Sunday in Chicago's Little Village. That's the neighborhood where 13-year-old Adam Toledo was shot and killed three weeks ago.
Police body camera footage released last week shows police chasing Adam down an alley. An officer orders him to show his hands, but less than a second later, after Adam has stopped running, his hands are up and the officer shoots him.
The shooting has led to demonstrations and demands that the Chicago Police Department make major changes.
