Two peace activists were stopped and harassed when traffic cameras claimed they were terrorists based on license plate ID.
John Catt, an 80 year old pensioner at the time and his daughter Linda (with no criminal record between them) - were stopped and their vehicle searched under section 44 of the Terrorism Act 2000 by City of London police. They were both threatened with arrest if they refused to answer police questions. Unbeknown to them the vehicle in which they were travelling had triggered an alert as it passed an automatic vehicle number plate recognition camera part of the cops Ring of steel around the City of London.
Now you see what traffic cameras are really for. Because the UK has more cameras than anywhere else, it's natural that the first political abuse happened there. This case is much like an earlier FBI database abuse against US peace activists, which showed us what these terrorists "watch" lists are really for.
"Watch" lists which accuse people of an infamous crime and punish them without due process of law are explicitly prohibited by the fifth, sixth and seventh amendments of US Constitution. When you allow such violations, government wastes your tax money to target and harass innocent people who are fighting for your rights.
