The guv'ment's tyrannical background checks stopping you from exercising your Second Amendment right to carry a semiautomatic handgun that can squeeze off 33 rounds in seven seconds or less? Just come on down to the Crossroads of the West Gun Show in Phoenix, Arizona, where undercover investigators working with Mayor Bloomberg's administration had no problem buying Glocks like the kind used by Jared Loughner in the Tuscon massacre. All you need to do is show some I.D. to exploit what some lawmakers call the "gun show loophole." In fact, one investigator was able to pay cash for a 9 mm semiautomatic even after telling the seller he probably wouldn't pass a background check. Instead of refusing the sale, as required by federal law, the gun peddler pockets the $500 and directs his shady customer toward the tent with the cheap ammunition. Watch:

City Hall says gun shows are linked to 30% of guns in federal gun trafficking investigations. Mayor Bloomberg announced the results of the investigation today, and said in a statement, "We have demonstrated how easy it is for anyone to buy a semiautomatic handgun and a high capacity magazine, no questions asked. This country must take two simple steps to stop more of the 34 murders that occur with guns every day: make every gun sale subject to a background check, and make sure the background check system has all the required records in it. Congress should act now, but gun show operators shouldn't wait."

After a similar gun show investigation in 2009, four of the seven gun shows targeted by Bloomberg each signed agreements with the City of New York agreeing to end no-background check gun sales. Of course, Tuscon shooter Jared Loughner bought his Glock from a Sportsman's Warehouse after passing the FBI's background check "immediately and without incident."
