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).
Sorry, the link's in post 8.
