I think this viewpoint comes from spending your time immersed in media that's so strongly biased that it's essentially propaganda. I'm going to take a wild guess and assume that you mostly get news from the type of sources that get linked on here, which are very quick on the trigger to print stories of alleged police misconduct, even if the evidence is rather shaky. These same sources virtually never print anything documenting the real-live effects of crime on victims, or stories of times when habitual violent offenders are difficult to bring to justice in practice, or descriptions of just how cruel and violent some of the worst offenders can be.
I think that people of a social class that rarely interacts with the legal system in any way, either as victims or suspects, are disturbingly easy to sway to one side or the other with a steady diet of propaganda. Spend a few years selectively listening only to stories of how terrible criminals are and how difficult to bring to justice, and you're ready to throw the book at anyone the police suspect without regard for the facts on the ground. Spend a few years selectively listening only to stories of police misconduct and abuse, and you'll end up kinda like Mr. graycat here.
To you, and anybody else feeling like this, I suggest, as an exercise to expand your mind and thinking, that you set yourself a project for a couple of months or so of deliberately ignoring stories of police misconduct, and perhaps even the sources that print them, and instead read only sources made up of or sympathetic to the police. Perhaps reddit /r/TalesFromTheSquadCar and /r/ProtectAndServe/. There's some other BBSes and news sources out there. Heck, here[1] is a good story from the police perspective of a violent stalker who terrorized his ex-girlfriend and repeatedly told the police every lie in the book in an attempt to get free and have another chance to hurt her.
And another one that's becoming a pet peeve of mine: > A police officer killed an unarmed person? Deliberate, unprovoked, unexcusable murder. Life or the chair.
What is this, Western movie justice or something? How does whether the suspect was armed have anything to do with whether his death was justified? This is terrible from both sides. A suspect who does not have a weapon is perfectly capable of being a legitimate threat to the life of a police officer. Many unarmed suspects have stolen firearms from police officers and proceeded to kill them with them. Or with vehicles, other weapons, or their bare hands. Many unarmed suspects have been legitimately shot dead while trying to steal firearms from police officers. How would you recommend dealing with them?
On the other hand, we do have the Second Amendment, and it is perfectly legal to carry a firearm with a permit in most of the country. The fact that somebody possesses a gun is not an automatic justification for killing them either. Maybe a little thing called intent is important?
