Impersonating a Police officer in the UK usually carries 6 months in Prison as punishment or at the very least a big fine if your lucky.
Saunders actually dressed up as a copper when he made that guy strip so he's likely to get fucked for this video alone.
It don't look good for Saunders as there's loads of other videos floating about where he's taken things too far.
If it was just one offence/video I'd expect Warren to grease a few palms with the BBBOC and get him off with a hefty fine but there's multiple videos out there where he's repeatedly and blatantly broken the law.
