Why should anyone have to prove what this gun isn't? It's no better than asking a black man to prove he isn't a criminal because that's who they show on the nightly news or that your dog isn't vicious because of its breed. If the BATF didn't consider it armor piercing, then why the fuss now? I'd rather ask the Brady Bunch, which ran tests showing the gun might penetrate body armor to open up their data and methodology for scrutiny first; just because they have video doesn't mean that something wasn't manipulated.
