Well, how about some positives.....
First, if someone is robbing your house and the bobby comes along and takes film of them leaving the scene, you would be happy knowing that you would not have to remember the details of those people who have just robbed you.
Second, if your spouse had just hit you for ten bells and the police had evidence themselves of the cuts and brusies it would make criminal proceedings a lot easier and less stressful for the victims.
It may be time to trust the police, these cameras would make criminal proceedings a lot quicker and save joe (and Joan) public a lot of money in saved resources.
I know that Big Brother is watching our every move, but in the places with odvious CCTV and police going around with cameras on their heads may help reduce crime in your area. Come on people lets at least give it a chance, at least the police are trying new ideas to stay ahead. With the government asking them to literally spend one third of their time filing paperwork, it is not always the bobbys fault when your crime goes unnoticed or unsolved.
Its time people writing on this look at life with the glass is half full attitude.
Rant over ;-)
