I know this thred is petty much dead but in Canada it's all if you want to take the risk. You have 2  choices 1.  Call cops (never see car again get low balled on claim). Or 2.  Catch  the person yur self beat them, they call the cops then you get assalt charges your self and watch the person walk.  It's a joke  and 99% of the time you don't have a happy ending and you might end up dead or in jail.
