I'm not a cop, and I also am happy to live in a country where there is barely any immigrant influx or low IQ minorities that would swarm any unprotected community. Yet still, it just takes a couple of minutes of non emotional assessment of the situation to see the great value of law enforcement.>but there may come a time when the people in that community, that you swore to protect, need to stand up for themselves
let's not kid ourselves, that the only time that happens is when there comes a new law that makes certain activities illegal, which strongly affects a sizable population. In any recent memory there weren't any laws passed in the western world that affected a large community and weren't ethical and justifiable.
The "standing out" that you bring up is almost always a 'chimp out' of misdirected anger and no comprehension of actual ways to solve issues at hand (or no ability to take responsibility for them).
In the rare occasions that the complains of the mob may be valid (like e.g. the whole Wall Street thing from few years ago) a lot of dangerous stupidity latched onto it.
A mob solves nothing. If there are laws you don't like - vote for your representative, convince your community to vote as well. Want it solved faster - sorry, that always ends up bloody.
There are laws for a reason as there are men to protect them. Not some "master". "the man" or whatever you want to personify your life's failures.
Get a job.
