Email i received from a guy about my craigslist gun post--(UPDATE Its getn good)

so i put my shotgun on there for sale.....check out this email!

We will be in touch with you don't sell this gun you are already in enough trouble for interstate solicitation of a firearm without a F.F.L. you sell it before we take it and 5 years just turned into ten flat fed. Time that's day for day .why do you think there is the NICS NATIONAL INSTANT CRIMINAL BACKGROUND CHECK SYSTEM .that is mandated by the F.B.I. I CANT BELIVE THAT PEOPLE STILL TRY TO GET AWAY WITH THIS AND IF THE PERSON BUYING THE GUN TURNS OUT TO BE A FELON YOU WOULD BE LOOKING AT MO RE TIME THAN THE FELON NO MATER WHAT IF THAT GUN GET THE SERIAL NUMBERS RAN BY A GAME WARDEN 5 YEARS LATER AT A HUNTING CHECK POINT AND IT'S NOT YOU IN POSSESION OF THE WEAPON BOTH THE SELLER AND BUYER GET A CHANGE OF ADDRESS LOOK IAM IN LAW ENFORCEMENT AND I DONT PLAN ON TAKE ING YOUR NICE GUN BUT EVERYTHING ELSE IS TRUE DONT MAKE A DECISION THAT WOULD EFFECT THE REST OF YOUR LIFE. IF YOU CA HAVE A WEAPON DONT BLOW IT FOR LIFE WITH A FELON charge don't think of selling it on c.l.they will come arrest you good luck with this and if I were you I would talk to a pawn shop owner and see if he would handle the transaction for a small fee sporting good stores want you or others to buy there gun not help you sale yours.
