From what I've read on the guy, he has a bit of an attitude when it comes to American government. So likely, when he was rather abruptly told to pull over on the way OUT of the country, he probably reacted belligerantly. From reading accounts of what happened, he got out of the vehicle and was told to get back in. Ok... usually if theyre going to search it, they *want* you out, dont they? Or is that just the proper searches on the Canadian side? When he got out, they probably yelled at him. If you're pissed already, and someone is yelling at you, how would you react? You might yell back. And since this is a border patrol person, that likely escalated into physical force. By their own description, this is when he finally decided getting back into the car might be a good idea, putting a door between him and the screaming violent dude. Instead, they grapple him to the ground. Not everyone will comply to physical violence under panic. For some, the natural reaction will be to struggle. I'd bet the truth is that the writer was a dick, didnt take well to being searched on the way OUT of the country, and Border Patrol, being pumped up over recent terrorism issues (did this happen after the plane bomber attempt?) decided to take their allowed parameters to the max and beat the crap out of the mouthy foreigner. He deserved being hauled in for questioning for being a dick. Not being pepper sprayed, beaten, and dumped in the elements on foot and coatless. Oh, and adding insult to injury? Then being told he could serve two years for essentially resisting the officers beating the crap out of him.
