You would hope so, but I was once struck by a car when the driver negligently turned without looking to see if anyone was in the crosswalk. Hit my head, permanently damaged my knee, broke my nose causing permanent sinus issues.... All she got was a ticket for failing to yield to a pedestrian. So there's no way a cop is going to get off worse than that.
Also, here in Seattle, a cop hit and killed a pedestrian in a crosswalk when he was responding at high speed to an overdose call without having his lights and sirens on (edit: to be clear, he was going 74? in a 25mph, pedestrian heavy zone). He did not suffer any consequences other than locals hating him and the system that let him off.
