What? after reading your first sentence many times it’s basically saying you’re of the mind that a criminal very likely has way more crimes that we’ve just haven’t seen so they should be prosecuted heavily for the one we did see just to make sure we get our prosecution-bang for the buck?
If the punishment is equal to the value of the crime then as long as the rate at which you are caught is less than 100% crime is a profitable option.
Not sure where you got that idea. No where did I express interest in punishing the perpetrator for anything more than what they were caught. My point is that their "solution" to justice does not solve vandalism the way that it they think it does.
