Hey all, My idea for a bank robbery involves a guy using a GPS/Radio Frequency jammer to block signals that cause a dyepack or tracker from going off. Is this credible? I've not come across a single real-life instance where this was done. But I assume it is doable. For that matter -- I wonder why no real-life robber has used the device to do that, especially in an era where thieves routinely hack into luxury cars using special gadgets to unlock the computer-coded doors.
