For those actually living in the US, we see a change in public views of police. More and more people are speaking against the police. Police continue to be ambushed and assassinated. People, like Dude, aid in this anti-cop sentiment with an endless stream of "look how bad cops are" videos and news articles.
Therefore what happens is people who are Not anti-cop defend cops. I have yet to meet a single person who thinks cops are incapable of doing wrong, unlike your unfounded accusation. We are simply tired of anti-cop sentiment and police assassinations.
This is not the first time you took a wrong view of things in the US and how it causes people to act and speak. You did the same thing to me a few weeks ago. Before you go launching into people in countries and cultures not yours it may benefit you to ensure you actually know more details. Rather than wrongly forming opinions and shooting off accusations with no real knowledge.
