No offense, but if I were you I'd try to get the hell outta that country. Don't go to France, though, that's like taking a step back in time, or another dimension... not quite sure. Just don't go there.
I was wrong, coincidentally I had to solve a similair case today for one of my assignments. I looked it up in the law and apparently when you catch someone in the act, you and everyone have the authority to apprehend that someone.
