Maybe on paper, but in practice they act with little if any respect for the communities they're in. For instance screaming at people and pointing rifles at their heads to "overcome" the language barrier. Or, as apologists phrase it, "use verbal warnings, show their weapons,"
Edit: Here is something else for the haters to consider:
https://en.wikipedia.org/wiki/Killology
After WWII, the American military conducted studies that determined a large portion of their soldiers were unwilling to kill people in combat. This was perceived as a problem and efforts were undertaken to make soldiers more willing to kill people. Among these measures was the use of human silhouette targets at gun ranges, a practice which is not coincidentally common for civilian police today: http://www.americantargetcompany.com/law_enforcement_targets...
It's not just a matter of whether an individual police officer was a combat veteran, but also a matter of whether he ever received training from a combat veteran (which is extremely common.) Look up Dave Grossman.
