Many of the evils in the US are rooted in the 2nd amendment and the NRA.
The police in other countries can take a much more relaxed attitude toward their interactions with the public because there's almost no chance of the person shooting them.
They could be, but are very unlikely to be. Despite the huge number of privately guns owned in America, the vast majority of cops will never be shot at nor have valid reason to shoot at somebody. Cops who constantly fear for their lives are operating under a warped view of reality.
I think it's a culture problem for cops. They hang out on cop forums, cop chat rooms or facebook groups; they read cop newsletters and generally socialize with other cops. These groups have the effect of amplifying stories about violence against cops, because those stories are sensational and of obvious interest to cops, and that amplification in turn gives rise to a warped perspective on how risky their job actually is.
2. Only the police should have guns.
Choose one.
The "only the police" almost makes it sound like that is what is being discussed around gun control laws.
The cops in the US are definitely more jumpy than I'm comfortable with - their natural reaction to a car door closing and someone (or is it just me, I look like a rake with an afro) stepping towards them is to touch their gun, because they treat every person as possibly armed & dangerous.
And it's not like I was in a high crime area either, all I needed was to know my way to SJC having missed 85.
I'm not "victim blaming" Kenneth Walker or Brianna Taylor here. Its absolutely the cops fault for messing up the no-knock warrant. But in a country with 2nd amendment, cops have the difficult job of entering homes vs armed neutral parties.
In the UK, cops can go in with nothing but a baton and be fine, because the UK citizenry don't have as many guns as US citizens do.
--------
There's a huge and fundamental difference between UK cops and US cops if only because of the 2nd Amendment issue. Each encounter with the citizenry, even if they are neutral, can end up deadly due to our huge proliferation of guns.
That stress in of itself could be making our cops more trigger happy, because US Cops enter life-or-death situations in higher frequency than other countries.
You're arguing that people should be deprived of the ability to defend themselves so that the police don't have to worry about the repercussions of trampling on their civil rights, and that somehow this will result in less trampling.
Ban no-knock raids (which have dubious legality anyway) and situations like this wouldn't happen. Better yet, end the war on drugs altogether. Kenneth Walker keeps his right to self-defense, Breonna Taylor lives, no officer gets shot, the constitution remains unviolated, and nobody goes to jail for victimless crimes. Everybody wins. It is astounding to me that people argue "disarm Kenneth Walker so the police can fuck up his (wrong) house stress-free" is a better solution than that.
Also, Indiana for example explicitly legalizes home defense against "public servants"[1].

A more recent and more famous example is the rapper Tupac who witnessed police beating up a guy for no reason. Tupac grabbed a gun and told them to stop, and when the police shot at him, he shot back wounding one, and wasn't found to have committed any crime. Randy Weaver shot and killed a federal agent and was exonerated at trial.
These are just examples from memory. I'm sure if you looked you'd find many more. It may not be wise to shoot out with the police, and you'd better be certain you're right, but you're absolutely permitted to use your guns on the police and kill them in some circumstances.
