What an example of the manipulation of statistics. Only 7,200 weapons of the 30,000 were submitted to ATF for identification and of this number only 4,000 could be traced and 3,800(87%) were from the US. The article then determined that the 90-87% figure was wrong and only 12% of ALL the weapons were from the US. If the 7,200 is a good sampling of all the weapons seized, then the 3,800 should be around 53%. But if the 4,000 was the good sample, then it would be 95%. The author assumes that the 3,800 was sampled from the 30,000 and not from the 7,200. Big error. There is another error regarding the 3,200 that could not be traced. The author simply tosses this number away assuming that they did not originate from the US. My best guess is that the percentage would be somewhere between 53% and 87%. Even at 53%, this is a huge number of weapons supplied from US sources (over 15,000).
