Its because of all these people complaining about so called 'unnecessary force' that our police seem to use thats caused the bloody problem and why are criminals get away with murder (very often literally).
As said above, we are probably have the softest police and one of the most lenient judicial system in the world.
I find it funny that many of the people who moan about 'unnecessary force' are the ones getting into trouble themselves (or have done in the past), and then these are the people who moan when there burgulerd or assualted and the police have little power to do anything (due to the weak system.).
It goes without saying that most people who hate the police with a passion, are criminals or ex-criminals themselves.
I think they should have more power in my opinion. If you stay out of trouble and out the way then theres nothing to worry about, and the criminals may think twice about what their doing. Simple really.
People who have had experience of this 'unnecessary force' should not put themselves in this postion to start with.
