You sound typical of someone who will jump up and down and make a lot of noise about an issue (which in this case you've demonstrated minimal knowledge about), but then if something happens to you, you're the first to scream "why didn't Police do anything about it?".
That's why I am a huge supporter of "community policying": if people in a community thinks it is OK to punch policy officers, take their guns, rob a store for cigars, gently push the store clerks against the shelf, sell loose cigarettes on the street, or to kill other citizens in their neighborhood without being harassed by the officers, they should have that right and I am all for them.
On the flip side, the rest of us has the right to implement stop-and-frisk, no broken-windows, and uphold laws as the people in my community desires.
Most of the democracies in the "western world" have degenerated into tyranny (of majority) and are full of free riders that suck the life out of the producers. Over the last few decades, it has gotten to the point where it is increasing irreconcilable. So splitting up the countries by ideology is probably the only solution -> everyone will be happy,
