I think stuie, that what is upsetting people (myself included) is that before there could be any kind of investigation, the police were giving it the whole 'he was part of our investigations, he jumped the barriers, he was wearing a oversized coat, he was in the flat we were investigating' etc etc
It must have been obvoious within 20mins of the guy being shot that he was an innocent man. the police didnt seem too bothered about anything but protecting their own and casting doubt.
this will surely come back to haunt them.
