Ok, people have put wholes in my theory of handing over a wallet to a mugger with fake money in it (apparently either the mugger will shoot you or the secret service will).
So here’s another question: can you devise a slim wallet that would have the same effect of “ruining” the mugging or identifying the mugger as the bank device that explodes ink/dye over the bank theifs and/or the money they took?
Would this work? Keep mugger’s gift wallet full of a couple $20 bills. Stamp the bottom of the bill with www.counterfeitbill.com or something and put the serial numbers up on the website indicated and explain that the bill was stolen and report to police with your email address (no name).
Ok, may not work, but I’m trying to think of a way to stick it to the muggers other than using a little martial arts on them.
