As mentioned...
One of the reasons he probably chose to try and smuggle the firearms in (and almost certainly didn't declare them to US Customs while outbound), is that sawed off shotgun in the picture. Illegal as hell in the US, never mind Canada.
Which makes one wonder if those handguns weren't really headed for the hands of criminals in Canada, especially that high quality RG10 revolver also previously mentioned.
This is the kind of guy that creates the justification, however poor, for the oppressive laws we face. He gets no sympathy whatsoever from me, and in fact I hope they lock his criminal *** up. Although at most, all he's going to get is a fine and lose those firearms and possibly the vehicle.
Would have been a lot more effective if they'd simply taken their picture, handed him back all his firearms, including the 7-11 Special, and then sent him back to the US where the Homeland Security boys would have been waiting with open arms to discuss his export habits and taste in shotguns...
I move firearms across the border almost weekly, both ways: handguns, shotguns, and rifles, depending on what's on the agenda. Have been doing that for over five years now. I declare them and get nothing but polite and expeditious service from the border dudes on both sides.
