Oh, who gives a Fiddler's Damn about international law! I mean, really!
I have no sympathy for those that desert an all-volunteer army. Pure, unadulterated cowardice, IMHO. I have no sympathy for them, and Canada doesn't need them.
That said, I have even LESS sympathy for cops that boot in people's doors without warrants, and arrest people without cause. There was no cause here because deserting the US Army is NOT a crime in Canada. There is a big problem with the police here.
CDN Bear, to enter a dwelling without warrant, the police require reasonable cause to believe someone is in DANGER of harm, or they must be in hot pursuit of a suspect.........nothing else should suffice.
