i think it did, certain officers were disciplined but i don't remember if any were dismissed, but i think the independent body found the force used to be reasonable, some people don't realise that even killing can be seen as reasonable force (it all depends on the circumstances). the force is not reasonable if you carry on using it when the other person is no longer a threat (ie they have been subdued).
one more thing on the kharhaz posts, in relation to the smell of ale on him, any police officer who did not give a breath test in that incident is a disgrace, if you had been drinking and they let you drive off, if you are then involved in an accident they should be ashamed. the police are not magic and thats why these tests exist.
i will say to anyone if you have done no wrong there is no reason to be worried about being stopped, the wrong attitude will not win you any favours.
if any of you think british policing is bad then i suggest you move to thailand and see real bad policing in action, most people are stopped just to extract money which goes straight into the policeman pocket (even though no offence has been committed, its accepted practice here, most people just pay it, i however am friends with a senior thai policeman who sorts things out for me so i just have to make a call when stopped)
