I have not noticed an increase in local crime, maybe in the city. I'm inclined to think its more from social values (criminals versus victems rights) and poor upbringing rather than the economy. Here are some of my approaches:
1. Situational awareness. Never presume that you are safe or protected.
2. Dogs trump electronic alarms. If you do have to go to alarms, get the most annoying, the loudest, the most flashingest-lights that you can afford. A silent alarm with a 5 minute response (and I think that isn't realistic) will only catch the drunks that are looking for a place to sleep.
3. Use motion detectors creatively. They don't have to be connected to lights.
4. Neighborhood watch. When I was 17, my motorcycle was stolen. I looked everywhere, talked to everyone. I found it in the shed behind the house of a neighborhood "friend". I stole it back, and yes I did.
5. DON'T shoot in the AIR. It wastes ammo. I am very accurate in placing .308 rounds and am only 200 yds from the shop.
6. In most states you can wear a side arm on your property. If you have people comming and going, subtly wear a side arm, under a coat, inside the pants. You don't necessarily have to brandish it but it does send a message.
7. Signs. I had trouble with trespassers and talked to the county sheriff. He asked if I had signs up saying that the judge would probably not do anythin to them if I didn't have signs. I took that to mean that I would have to take care of my own problems. The only sign I have is a "We Don't Call 911" sign, with a bunch of large calibur holes in it.
8. Booby traps are illegal. Dogs sleeping in the shop are not.
9. I have to ****** poachers (deer and turkey) off the property every few years. News gets around and I don't have to for a few years.
10. Motion activated cameras (game cameras are cheap) document the crime and the criminal. If the lights are motion activated also, the chump won't realize that his picture was taken also.
11. Remember that locks only keep the honest out. You can buy a pick gun from mail order for $49.00 that picks most residential locks in seconds.
12. Razor wire and hot wire fences are only good if they try to pee on it. Well it does establish a good demarcation of the perimeter.
Sorry for the rant but I get really ticked off at cowards, cheats and bullies.
