Some of the  boss are bastards, they can do anything so be littel carefull. If you want to scare him, talk to lawyer take advice, they give free advice. And tell the lawyer to call your boss and ask not to bother  anymore,may be lawyer willcharge you some 100 or less.

If boss give that video to police and complain about your stealing which that video may prove. The police will come after you and if they put in jail for one night also, the record will be for every which may hamper in ur future.

so take it seriously and solve it without going to cop.

best of luck
