I don't like being disturbed when sleeping in my car for a few hours when I have spent the 1st part of the night running over some hills as part of my BGR training. The statements that "anything could be happening" is rather strange justification for being curious. On the flip side we have a very good local officer Hefin who gets the big picture and the difference between people who want to see the Police as a service to work with and those who see the Police as stopping them doing whatever they want.
There does need to be a prosecution by the pushing Police Officer over the death of Ian Tomlinson for ordinary people to have trust that Police misconduct will not be covered up. The outcome of such as case is up to the jury, but that a case must be brought against the officer in question is very obvious. Other members of society have been before a jury by now, the Police can't be left off when appearing to step so far out of line. If the case finds the officer innocent, then its is an end of the matter.
