Police Brutality and Ian Tomlinson?

For those not keeping up with the news a man died from a heart attack at the G20 protests, police said it was nothing to do with them and when they moved in to help after the collapse they were pelted with bottles.

Now we have a couple of videos being circulated, most importantly one shot prior to Ian Tomlinson's collapse. GMTV showed us only the most damning bit, BBC showed more and as a result of which provided a better context.

Here's how I view it - the police move in down the street, presumably in an attempt to corral the protesters. Ian is seen on the right simply sauntering along, hands in pockets. At this point the officer with the dog (brown) to the left seems to purposefully move around the bollard in front of him so as to intersect with Ian's path, as the camera moves right we see that another dog (black) handling officer has moved in from the right both officers seem to try to move Ian away with a light shove. The black dog then starts to follow and harass until pulled back in; Ian appears to be trying to walk away.

However this action puts him on a course with the line of police who have moved in ahead of him. At this point an officer who previously seen second from the right with a baton casually resting on his left shoulder moves in around the black dog as it was harassing Ian and as it's pulled back sends Ian sprawling. Judging by the distance he moved across this was one hefty push.

Two passers-by help him to his feet while the rest of the line of police halt and mill around. The officer who performed the shove is seen in the background in the same baton on shoulder pose before he walks off to the right and is lost from shot.

In a second video, which I can't locate a link for, we're shown the aftermath with Ian collapsed on the pavement surrounded by police. A bottle is thrown which misses everyone and as one the protesters turn to prevent any more.

We all know that facts get blurred in the moment of action, but look at the first statements given out by the police -

Deny responsibility.
Focus attention elsewhere.

This is the the standard knee-jerk reactions we'd expect from any private firm that looks out only for itself and yet over the last few years, as the police have been given wider powers they seem intent on misusing, this appears to have become the standard policy of the police force. An organisation we pay for supposedly to defend us.

[Additional - Just a thought the SOP appears to be -

1. We had nothing to do with it
2. Yes we did it but he/she/they deserved it
3. We've got a dangerous job in trying times.

In this case we seem to have skipped past two because no-one had any thought that the police might have been involved. Now the videos are out expect a lot of testimony that Ian Tomlinson was 'acting shifty', or getting into 'fights' with the police prior to the video footage]
