Also, I wouldn't underestimate the abilities of British law enforcement.
Are these the same British law enforcement who send out letters to burglary victims without ever visiting the scene of the crime? Who claim there's no CCTV in central London when someone is mugged? Who don't even bother showing up when cars are stolen and just post out a crime number?
Which British law enforcement is there that you're familiar with?
It is very rare to see any police officer in London, i thought they had CCTV everywhere?
