we were talking about bombs here; first the jail break, and then which wire to cut, if ortodox, (black, red, white), the black is the neutral; better idea, find a phone line, cut any wire, is indifferent! About bombs, old bombs, old expert on the 70ths with pressure weight counters, etc etc...and how did they remember pressure weight alarms?, anyway, water will solve the floor alarm, on that case! about today's bombs, and fused which are not radio jammed...you can actually forget the fuse...you just place the bomb inside a car, with the radio playing loud enough! or, place the bomb at the traffic electronic signs!
