i will say that this has changed quite a bit from the 1950s and 60s until the 90s.
It used to be that if you were pulled over in traffic and handed the cop your driver license with a folded $10 bill behind it, he would hand back the license and tell you to be careful. Many drivers kept a $10 bill behind their license in their wallet for just this purpose.
Those days are over.
It takes at least $100 now.
Seriously, few Chicago police officers are going to accept a bribe. It is just a few in very cynical and corrupt corners. Criminals who want to bribe police officers need to find officers who are are desperate for money or hooked on drugs.
