Cops teaming with criminals

I agree, cops should be allowed to do this, however it can be an issue. For example, if a cop is aiding a fugitive escaping, other cops giving chase are put in a bad spot because they risk getting punished themselves if they hit the corrupt cop or even kill them by friendly-fire. Even worse, the corrupt cop may choose to die in a car explosion on purpose to screw over the police trying to stop them.

That's a good idea. Here's what could happen:
If a cop gets spotted by other police officers riding in a vehicle with a suspect, he gets a warning.
After 1 minute, had he not left the car or ejected the criminal, he becomes tagged as a corrupt cop (maybe even change his name color from blue to another color).
If this happens, other officers can arrest him or take him down if he fights back, taking care of the "friendly-fire" issue. If he gets arrested X times for it, he could get demoted.

If a cop stays in the car with a suspect fleeing from a police officer after 1 minute, and if the suspect is not cuffed (blip color isn't changing), he should go off-duty and be marked with the most wanted level 6.
