just a pity there was no sound recording of what was said, it looks as though there were words being exchanged between him and the officer(s) to his right as he walks, be nice to know what that was, and would also be nice to see what went on in the seconds before the filming actually started. the bloke,s dead and yet again its a clear case of police brutality in the eyes of the world, but somehow i think theres a wee bit more to it than what meets the eye. he certainly looks unsteady enough on his feet before the push, so was he drunk and remonstrating, even threatening, in which case the response of the police could be seen to proportionate and justifiable and that what happened afterwards was just sheer misfortune. on the other hand may be he was entirely innocent in which case the police response was not acceptable.
