The entire article reeks with fallacy. If the guns pulled from the stack showed that 90% of what was pulled from the stack came from the US, then anyone who has passed high school statistics will tell you that one can infer that 90% of all the guns, +/- 5%, came from the US. The author twists math like a pretzel to come to his "17%" conclusion, the man is an idiot. Mathematically speaking, Obama is on much firmer ground asserting the stat than this other moron is in his conclusions. This article is koolaid, brewed for the RWNJ crowd.
