I was just heading off anyone that would have made that connection on their own. I'm not familiar with the situation in question here, but just from what you described, the police may have been focusing on the group they felt was a bigger threat to themselves. I mean, if one side of a protest is anti-police and the other is pro-police, it could be seen as reasonable for police to expect violence against them to come from the anti-police side and treat them accordingly. That doesn't necessarily mean they are showing support for the pro-police protestors, just that they don't see them as a threat and thus don't police them as heavily as they do the anti-police side. Of course I must reiterate that the above is just based on what you described without any further knowledge of the particulars of the incident. There may be additional details that do, in fact, indicate that the police were using their authority to bully political opponents.
