actualy, from more then 5 or so feet away, to me that would instantly register as a block of c4 with an indicator light and a 9v battery as means of detination. alot of these security guards are former military and if i had been in iraq or afganistan, i probobly would have reacted the same, if not worse to somthing that looked like abomb.
Only in the movies do bombs have flashing lights and wires everywhere. :-?
If I was going to bomb a airport, I certainly wouldnt dangle batteries and breadboards around myself.
