David,

Really sorry to hear about this and think the monitor camera that can record digital images on a computer is the way to catch anyone red-handed.

It seems like burglaries are on the rise in many places because of economic hard times. Could be that is what you are experiencing. No excuse for illegal actions of these douchers, but possibly a cause for thinking things will get better when economic conditions improve.

Unfortunately, I believe any form of booby trap is illegal. Too many criminal rights.
