I suspect that, after his warning, the crime rate may actually go DOWN. And even then, the response to most crime will not be to try, convict and incarcerate the perp but, rather, have an ambulance* come and pick him up. That will save a ton.

In Eastern Ky. what this sheriff is saying is what others have said for 40 years that I know of firsthand. If you know who is breaking into your house they tell you how to take them out and get away with it. If the leos have had problems with them in the past they well tell you how to end everyone’s problems with the thug and give you a number to call of someone who is aware of the situation. In my case it was a Lt. in the state police. All the thug has to do is attempt to rob you again.
