Demonstrators chanted, blew whistles as a symbolic way to alert police of their presence and used yellow caution tape to rope off an apartment complex where a naked man was gunned down by police several days earlier.

Protesters marched Saturday at the same time a visitation was held for Anthony Hill, 27, who was shot near his apartment complex by police Monday.

“We're out here because there's an epidemic of police murder that's happening around this country. From Ferguson (Missouri) with Mike Brown; to New York (with) Eric Garner, and here in Atlanta with Anthony Hill, that was shot, killed and left naked to die in the streets. We say that this unacceptable and it's up to the people to stop it," a demonstrator said.

Hill was naked when he was shot and killed by Robert Olsen, a DeKalb County police officer.

"We need a civil and criminal justice system that’s going to hold people accountable," said Leea Allen. "To go through that full process and that's what the law guarantees us and that's we're asking for."

In the short term, the group says it wants Olsen to be convicted of murder. In the long term, the demonstrators want reform in the justice system.

"We need complete revolution. We need to have trust in our police and in our law enforcement," Allen said.
