I was puzzled by the failure to keep him longer after they detained him. In the US a person can be held for up to 72 hours on what is called a probable cause hold so that the cops can investigate without the suspect taking advantage of the time delay and taking off.

I would like to think that law enforcement would hold someone who appeared at an international border with a bloody chain saw, but you are correct; the Mounty who stoppedhim did hold him and only let him go when the higher ups told him there was no basis for holding him. Funny thing, life, isn't it?
