That's a sweeping generalisation. I participated in the big march against cuts and the police were very respectful and only moved to contain those who were participating in violent behaviour (trashing shops, etc.). The vast majority of protesters were peaceful, treated well, and not kettled or horse-charged - a direct response to the previous condemnation of those sorts of tactics used against the students in the previous marches.
I know what they are, but I don't think that any such thing justifies the sweeping generalisation the previous commenter made. The police have been employing a range of tactics, and some have worked better (in terms of public opinion too) than others. Kettling, as far as I have seen since the public outcry over its use in the student situation, has not been used against peaceful protesters since.
