Encouraging the public to spy on each other isn't exactly new but does seem to rear its slightly Orwellian-looking head every now and again - tube passengers and teachers have both been encouraged to cast the beady eye of suspicion on their fellow travellers and young charges in an attempt to sniff out terrorists and London's suspicious photographers were until recently fair game for security guards.
It's one thing to encourage people to be vigilant but the level of snooping frequently descends to the ridiculous and promotes a climate of fear as well as providing opportunity for harassment over behaviour which is not illegal and not even particularly unusual. The Met countered the ban by saying somewhat defensively that 'the ad addressed the issue that terrorists lived in normal communities and what sometimes appeared to be insignificant behaviour could potentially be linked to terrorist activities' though it seems they have overlooked the fact that using cash and keeping to oneself are also common in normal communities. So if you live alone, make sure you rack up your credit card debt, take your curtains down and put a sign in your window saying 'Im a misanthrope, not a terrorist'.
You can hear the offending advert on the Met's website.
