Epic fail

I agree he may have been a little heavy handed but she was confrontational. Aggressively pushing forward and then it looks like somebody else (just out of shot to the left) pushed him.
I think the pushing (which isn't obvious to see in the video) is what caused it to get out of hand slightly.
The instructions seemed simple enough, just "get back", Simples!

why should she, she is at a peaceful protest which is (barely) allowed her under British law, those police put themselves right in the middle and were clearly acting in a very agressive manner. Since when have you had to jump whenever the police say so or risk being beat with a metal pole?!
I was there at the G20 protest the day before and the police were taking the fucking piss. had we been let out when we wanted then there would have been no windows smashed on the empty RBS, no bottles would have been thrown. had the police let me out to get a fucking drink of water when i had wanted then we would not have had to push them out of the way to leave. They handled the whole 2 days of protest in a menner which shows their true hatred of protests.
