What Scott mean don't prevent crime? Put some armed pig(not rent-a-cop) in a store and 9 times out of 10 cats will cool out. They used to post up outside some of the bars out here in the 90s, best believe we chilled when they were there. Cats will plot entire crimes around police patrols. Most folks ain't trying to get a bunk.
Them pigs post up on the block and look at you, you ain't doing shit in front of them.
I could go on , but only academics who never did shit think pigs PRESENCE doesn't prevent crime a lot of times. Shit, just put a pig on the highway with a radar gun and watch all the break lights when people see porky.
Now not solving crime, I completely agree 10000 percent. In my experience, without CIs or some snitch pigs ain't fucking shit. They don't know who did what out here without some snitch they have in place feeding them info and where to start digging. And don't call these bitches for a break in and expect them to do work. If you got someone missing, best hope you got money for a PI or a plug with the media.
As for pig training,
