The U.K. law is probably the oldest and most archaic set of conflicting rules in the world! Is it any wonder that when some changes are forced on it problems arrise?
Maybe it is time to look at the "rules" and change them round a bit!
I find it incredible that nobody can tell if taking a certain set of actions is legal or not untill afterward. If I consume a couple of pints of beer and drive home nobody knows weather I am over the limit until I provide the breath test into the big machine at the police station! Result, loss of driving licence and livelyhood! Similarly it would appear that video evidence of police officers "arresting" a woman at a nightclub by physically draging her (on the floor) down a flight of steps, lying on top of her and punching her at least 4 times with full force, is O.K. because that is how the police are trained! I repeat this is in the U.K.! Mixed messages or what?
