I like the booby trap idea the best. We had our house broken into 5 years ago, and we knew they made 3 different trips by the 3 identical oil patches on the concrete....only thing they left were the beds, couches and refrigerator. 8O Our illustrius PD said that the only thing to have is security video, BUT..it has to have the time/date code stamped in it to hold up in court.
