This doesn't suprise me. I hate crossing the boarder not because I have something on me or have done anything wrong but jsut the fact I know they can rip my car apart and leave it for me to put back together.
I was once held up at the Alberta/Montana boarder for a few hours, they took my car, searched it with dogs and then they gave me a huge hassel about a lighter than had marijuana risidue on it.
I just told them they searched my car and found nothing, the risude could have come from someone borrowing it at the bar and I was not sure what the hassel was as what was I going to do scrape off the risidue and sell it for big money down in the states
They know what kind of power they have and they definetly abuse it sometimes!
