In 2018, Chicago police officer Joseph DeRosa pleaded guilty to a felony in Michigan, admitting to resisting and obstructing police during an allegedly drunken meltdown at a casino. According to a police report, DeRosa kicked a Michigan officer in the face.
Under Illinois law, cops convicted of felonies lose their certification to be police officers in the state. The idea is to keep them from hopping from one law-enforcement employer to another.
