Billyfred, stop being foolish. People don’t usually want to park illegally now, the fines are deterrant enough. Most parking violations are accidents. Do you really want tons of people dying because of an accident?
Also, Jabor is right. Think of it this way. If kidnapping had the death penalty, then actually killing the person you kidnapped doesn’t hurt you at all. If parking had the death penalty, then shooting the cop who tries to take you in and running wouldn’t hurt you at all.
