People always draw a comparison with the states - they have armed police and huge gun related crimes. But try looking at Canada - armed police, and a level of gun crime about the same as us. 60% of US policemen who are shot, are shot with their own weapon.
Perhaps if the police force was allowed to spend it's money in it's own way we'd have a better system. Police atm have to employ people to enter and transfer data between computer systems, and policemen have to spend between 30 and 60% of their day doing paperwork. But whenever they ask for a new computer system, the goverment always tells them to spend it on more policemen instead (for comparison, the money they've asked for for years works out at about 4% more coppers).
