Ok, I read the affidavid...
1) Olofson specifically requested when loaning the gun that it should not be fired in the 3-round burst position, because it may malfunction.
Therefore it's entirely possible that he just shoved the selector in without connecting anything and honestly didn't know what would happen.
In addition, none of you big-brother-lovers have offered any proof that the simple act of adding an M16 stock selector to an AR-15 is a federal crime. Please show me the money, because as far as I know we're not talking about anything other than swapping out one lever for another.
2) The claim by Kiernicki is that it fired 3 round bursts on the range. The claim by BATFE is that it fired all 20 rounds in the mag both times they tested. Somebody please explain how it goes from two 3-round bursts and a jam, to 2 mags of full auto, with no further modifications.
3) It also claims that Kiernicki fired the firearm twice in 3-round burst, and that it jammed after the third try. What is a "jam" in this sense? The affidavid says that it fired twice, but he tried three times. Doesn't that tell us something?
4) The affidavid also adds extraneous information that is IMO quite obviously only added to bias the reader. So he owned a 50 cal sniper rifle - so what? What does that have to do with the case? How do we know it's a Barrett, and not a muzzleloader with a scope? And since when are pliers and vises evidence of wrongdoing?
He was also selling parts - again, so what? What does that have to do with the case? Was he selling upper receivers (or lower, I don't remember which) - which is the only FFA controlled item? What is unauthorized use of an FFL number assigned to another individual - is it possible he was doing legal internet transfers and that this is just added as fuel for the fire?
5) Finally, and most importantly, when the hell did the BATFE become our friend? Why is everyone so eager to take an at best sketchy affidavid and send someone to jail for doing something which hurt nobody? Where are the philosophical discussions on how NFA 34 undermines fundamental founding principles of this country to begin with, does nothing to curb crime, is generally only used to put overly dense hobbyists in prison, and undermines the rule of law in this country?
