The problem with border searches making a mockery of rights respected (for the most part) elsewhere in the nation isn't limited to the United States. Up in Canada, courts (and lawyers) are asking the same questions: how well are old, pre-smartphone laws holding up to today's reality? Everyone already knows what the answer is: not well. The question is: when will the Canadian government do anything about it?

Canadians -- like Americans -- have the right to be free of unreasonable searches. Unfortunately, just like in America, this right seems to evaporate when one approaches the border. According to the Canadian customs law, border guards can search a lot of stuff travelers carry without a warrant.
