There are people here on FR defending this publicity-seeking idiot, saying he did nothing illegal. They probably defend his dog for killing a baby sea lion, too.
I'm not defending this idiot for being a hypocrite, but I will defend him on this. He did not break the law. Period. Read the form in link 7, read the instructions on page 4 of the form. What he did, or stated he was going to do, was not illegal. Actually, according to the gun shop itself, he hadn't even completed the form for the rifle, yet, because he couldn't purchase it at the time due to a waiting period on used guns (to determine if they've been stolen).
Personally, I feel like I’m defending common sense (and reading comprehension) from a mob.
Show me where what he did was illegal. I've provided a link to prove to you what he did was not in my post #7.
He's certainly a hypocrite, which is what we should be calling him on. The AR-15 with the 30-round mag wasn't the only thing he wanted to buy. He actually purchased a 1911 in .45 ACP, as well. He took it home that very day, presumably after completing a 4493 for that purchase.
