The guy was pushed over by a police officer without due cause. That is a fact which was plain for all to see. I believe thats common assault . How exactly was that justified by belligerent behaviour 20 minutes earlier or by officers 'under stress'?

From what you say I assume that you consider that people do not have the right to lawful protest. Perhaps they should all have beaten within an inch of their lives just for taking up police resources which should probably have better spent on some Royal walkabout.

The recent report of the Bloody Sunday enquiry perhaps sums up extremely clearly the depths to which the Establishment will sink to murder civilians in cold blood and then work extremely hard to cover it all up in order to protect itself.Then there is the Menezes case but perhaps Jean Charles was also beligerent to an official that morning so clearly deserved to be shot dead on a tube train with the police subsequently fabricating a story about his jumping over barriers and running away therefore creating panic and uncertainty amongst their officers and hence contributing to his own death.
