Sometimes things are what they are. Don't go looking for examples to fuel your anti-police paranoia just because it makes you feel good. It's tragic Ian passed, but there's no evidence he was somehow murdered by police.
Quite the opposite. I'm demonstrating there is nothing to be of controversy here. It's pretty clear what occurred here (we do have many of the facts now), yet many want to go off on some wild conspiracy theory. That's fueling controversy purely for the sake of controversy.
With that said - I do believe all the cases have been made, and people will see what they want to see, regardless of the truth.
Some people have good reason not to trust police reports, as abuse of authority is rife within many districts in the US and UK.
This does not mean that we would disagree with what an official independent report would state because "It has to be a conspiracy", or any other garbage reason -- it just means that we disagree that the outcome of the official police report is necessarily correct, because of the bias police reports can hold.
