Chairman of the committee Keith Vaz said the public "clearly don't understand" the reasons for using kettling and other public order strategies.
"What's acceptable, what's within the police rule book - the use of distraction tactics, for example, slapping or hitting people - shocked the public," he told the BBC.
Wait. Unprovoked violent attacks on protesters is an official police tactic?
You're right, Vaz - I don't think the UK public quite understands that.
