It's not unusual to read the final recommendation and wonder who the heck they reached that conclusion based on the facts they presented.

I would take it farther than this though and say the ignorance often shows in groupings. . .like, it seems not to far fetched that the would compare an Ed Brown 1911, a Llama and a Colt DA 1911 in a 1911 comparison. Then, to make matters worse, the Colt DA would win because it had some inherent safety because it is a DA.
