I always wondered why they never booby trapped the stupid things to that if the bad guys take a hold of them, they get zapped with a couple hundred volts of electricity.
Of course, the good guys are wearing Batsuits that are insulated, so they don't get harmed.
Or, they could set off those little bitty paint bombs like banks use when they get robbed.
Or, inject them with a sedative. Or gas them with a sedative. Or go off like a car alarm.
Goodness me, there are so many ways to take out the bad guys that have the nerve to steal your stuff!
