yea they would do something about my mom has been a postal worker for 20 years and she has come across that before on one of her runs, what SHE does is take it back to the post office and turn it into the POLICE, now im not saying you would get cought but DO NOT put a return mailing address on the envelope if its a local send you dont need one i dont think but you know, its not really the smartest thing to try, so if your asking if we condone this ..... HELL NO i wouldnt try it. but thats just me.. PEace!
