Consider the bias of people making such statements. Society hasn't actually moved to that point, but many anti-police advocates want you to believe it has. In actual reality, most encounters with the police don't result in arbitrary killings.

Moreover, repeating such statements only makes the situation worse - especially if its repeated on the (inter)national media scale. Most police officers are normal people (just like most people in general), but when the society in general starts treating them as enemies, it doesn't help them doing their job in peaceful and responsible manner.

If police officers were intended act like normal people, they wouldn't be carrying military equipment.

Your implication that people who carry military equipment aren't meant to act like "normal people" would be incorrect even if it were the case that most police officers carried military equipment (which they don't.) The actions of the police in the posted article don't really support that assertion either.

US is a pathological case. I wrote this for the sake of fellow Europeans as well as the rest of the world, because I see the increase of anti-police sentiment (including linking to that "Don't talk to the police" YouTube video) in countries where it's not warranted.

Yeah, that's not the place we are in.

If you take anything but a ridiculously short term view, the expectations of how police will treat people today are far higher than they have been in the history of the US.

We still have to recognize and confront the remaining problems, but national media attention and prosecution of police who commit murders is a step up from police committing murders with no consequences.
