In reality, “death is around every corner” is an intentional training method pushed by the police themselves. Evidence-based training would likely go a long way to making police public servants again, and improve community relations a great deal.
Anyway, I have lots of friends in the law enforcement world, and almost all of them are happy with their careers.
Also: on average, being a cop is just not that dangerous, and it gets less so every year as crime rates drop. These are just the facts. In the vast majority of situations police will be the better armed and trained party. Much different than other public servants, who often have to deal with the same public and the same scrutiny for less pay and with worse protection…
I'm not sure what it would take to get there in the US, but whatever obstacles are in the way to true reform are not only the fault of police, but are pretty deep-seated social issues.
Particularly, the US has a political legacy of expediency being successful and popularly supported, while adhering to principles is seen as pointy-headed pedantry. When it comes to the portrayal of law enforcement and criminal defense in popular tv shows and movies, more often than not, protagonists bend the rules to catch criminals who otherwise use procedural loopholes to evade justice. So, the people that adhere to principles are the villains, and the people who bend the rules are heroes. This social current manifests in real, actual political life when partisans promote or cherry-pick gossip and news that they themselves know are false, but if widely believed will harm their political opponents.
This trend hits US cops specifically in two ways. The first is that bending the rules is expected and sticking to principle is not rewarded. And that's not by "the leadership" but by you, you reading this - if you have ever thrilled to a hero bending the rules. The second is that even cops who do stick to principles can be savaged in the media with a presumption of guilt because everyone knows ACAB.
How do we fix all of that?
Is that a thing that happens?
