I will say that the US Police
have to deal with things that Europe would have difficulty imagining are even factors, and that on a few occasions, well above (evidently, it would appear that the gun ownership community suffers from a similar predicament as they in regards to coverage: much like one bad policeman speaks for a thousand, the same could be said for gun holders, who are ironically lumped in the same group as said bad cops in the heads of those against them largely due to the "us versus them" mentality), objects such as armored cars and anti-materiel rifles are something justified to do their jobs, but they have actually become more restricted in theoretical procedure in spite of their more noticeable..."outbreaks"; This is all part of a rather vicious cycle where the trust between the police, or going further, the government and the people have grown to distrust each other, and as a result are in some sort of legal/arms race that could be described as follows:
-
Police abuse their powers.
-Public treats them as subhumans as a result, leading to more hostility between the groups. The outcry causes as change in procedure, which leads to more work for the police, but does very little to actually make them as an entity any less corrupt.
-Feeling alienated by the public, the police return that hostility, and feel less obligated to defend the public.
-The police abuse their powers yet again, as they have little reason to work for a public that loathes them beyond what is needed for a paycheck.
-Police are hounded on once more, provided they're actually caught. Scolded by the judges, perhaps one or two loses their job, but nothing groundbreaking ever happens.
-To occasionally give spice to the cycle, police are given better equipment by "the Feds" in order to deal with the undoubtedly dangerous populace, in a world of "terrorism" and "violent religious zealots". Never mind that they're not actually authorized to use it half the time, but the public sees this as them becoming more militarized and a sign of their corruption, decrying them further.
-Police see little reason why they can't bend the rules one and a while, being the law after all, and use said equipment in order to spite and instil fear in the public.
And such a cycle will continue ad-infinitude until somebody changes both the relationship between the two groups, as well as the culture of the enforcers themselves. Unfortunately, I have no idea how such a thing could be accomplished without wiping the slate clean in some areas, which would result in a bunch of unemployed ex-officers unable to retain their jobs being treated like criminals (the fact they might only
technically not be none-withstanding) by the public, reinforcing the negative mentality that caused the issue to rise in the first place.
