I remember Ed Bradley doing a network magazine show some years back, on how easy it was to buy machine guns. He claimed that little wannabe gang bangers in the projects were buying machine guns for "$50 on the street."
So, he found this little kid, crouching in the stairwell of his building, guarding his turf I suppose. The kid would flash, but not really show some sort of black rifle. What it really was, when he showed it, was one of those cheap BB guns that look like a cartoon M16, with the buttstock broken off, and only the pistol grip left. So, that was the "$50 machine gun".
Well, so much for the illegal gun trade... if you could really buy machine guns for $50, hell, I will take two. No, here's $500, I want one each for Christmas presents for my entire extended family!
