Chicago police have been involved in at least eight shootings in the last two weeks, including five that were fatal.
Saturday's marchers claimed the deadly force has been unwarranted.
enough is enough. If you cant' do the job, you're scared to come to our neighborhoods, maybe you need to find another profession," said Ashanda Harrison, the aunt of a shooting victim.
"You expect them [children] to get shot, growing up in the city, by some thugs on the streets, but not by the Chicago Police Department," said another woman attending the march, who was identified as a shooting victim's mother.
The Chicago Independent Police Review Authority is investigating the shooting incidents.
