Firn,
But security is little more than making the situation more secure or uncomfortable enough that the problem simply moves on to someone else's backyard. In rural USA, that may only equate to shifting the thugs several hundred yards into an adjacent neighborhood where the same local law enforcement will still have to deal with the very same problem. No ?
Their goods may end up being more expensive, but we still did not get rid of them.
Why not just terminate the problem where it grew roots instead of sending them into the neighbor's yard ?
