I don't think that that's quite a reasonable take on things either--I do not believe that officers wake up every day going "Man, I hope I get to shoot some kids today".

Such hyperbole makes it harder to understand their position and hence to effect useful change.

Very few police ever fire their gun during their career. But an officer who killed a man by my work 2000, that was his third fatality. All same MO, mentally ill guy with a knife, close the distance under 21 feet and shoot.

No, but some police do seem to have a mentality where they think they need to be a substitute jury or provide some of the corporal punishment the legal system omits.
