I watched a few minutes of a show last night on cable about guns on the border at Mcallen I think it was. The first scene I saw was a reporter talking to a BATF agent in his office, and he pulled out a receiver with barrel support for a M2HB, and said these kinds of things can be bought at "any gun show every day", then the astonished (imagine!) reporter asked "You mean these things can be legally purchased in the US?" When the ATF agent said "yes" that was enough for me. Show channel turned off. My own kind of censorship.
