PHILADELPHIA (AP) — Six black Philadelphia police officers have filed complaints with a state anti-discrimination agency claiming their white supervisors are racist, corrupt and should be removed from their jobs.

A group that represents black Philadelphia police officers says the complaints against two narcotics bureau inspectors include allowing a worker to park his Confederate flag-decorated truck on city property, referring to black civilians as “scum” and calling black civilian killings “thinning the herd.”
