rude, debate all you want about legality and intentions. I could care less the legal aspect.
Mark said he wanted to show how easy it was to get an AR. His choice of purchase was anything but easy. It was one of the hardest way to get one fast, he bought used and had to wait.
That’s like saying I want to show how easy it is to buy an “evil assault rifle” so I choose to buy an AR with a silencer.
OK fine, it’s yours. Except you have to apply and pay for a special Fed Stamp. How easy, 90-120 day wait?
And that's perfectly fine. I think he did it for political purposes, also. But he didn't violate the law, and those who disagree with his political purposes shouldn't claim he did.
