This is what happens when you quit enforcing laws.

Of course I can make it simpler - those things you reward you get more of (laws are not enforced so criminals continue to commit crimes)
Those things that you punish you get less of (arrest, convict and put in jail criminals the crime rate will go down).
There was a rare car chase just the other day in Seattle. The cops chased after a car that had some folks in it that did a drive-by shooting.
Just a stolen car and a smash and grab? Forget about it.
