you'd be surprised....lol....crooks aren't the most intelligent people in the world....just read a case where a guy took a cell phone, put it on Craig's List...the guy who it was taken from happened to go on Craig's List for a replacement, saw the identical phone, and yes...you guessed it, purchased his old phone back, numbers still intact...the perp, put his return address on the package...and I could go on and on....
