I'll tell you what
If the man think this works and the EU thinks this is a sensible thing to protect against terrorists then fair enough.....
That every person wrongly labelled a terrorist can sue their (the inventors and EU backers) asses for libel.
How long do you think you'd hold onto your money when the number of nervious flyers is 5% and the number of terrorists 0.00001% and terrorists are often calm. Yet if you were not prepared to defend against the libel claims, why are you so free to label people terrorists based on your algorithm?
How's CCTV going? Stopping many crimes? Or mostly used to enforce parking tickets?
How's the MET's anti-photo campaign going, stopping terrorism?Or mostly just making people suspicious of other innocent people?
These dipshit ideas only happen because the people involved don't face the consequences of their actions. Was the man responsible for the MET campaign sacked? No!
