yep slow them down till you get the bat like you said. im not from the safest place in america so i know people who steal and how to deter those people.
i know of a system that was solen in less that 10 minutes with 5 people going slow and taking there time. i was a HUGE box with 2 memphis MOJOS and 2 big amps, but the victim had no alarm on his cavi...the whole operation was orchestrated, practiced, and timed. some serious stuff goes on out there, they were in the car in 13 seconds...
