Part of the deal in a well-run society is this: the citizens agree to abide by the authority of the folks in charge (police, etc). The folks in charge agree to HAVE a well-run society, with rules fair to all and enforced to all.If the government doesn't prosecute the criminals and protect the citizenry eventually the citizenry will say enough is enough and take matters into their own hands.
This is breaking down, if it hasn't already. There is clearly several sets of preferred citizens (or non-citizens, as the case may be), and a multi-tiered justice system.
The result is a vigilante system similar to that if which you speak.
Unfortunately, the powers that be want us divided and at each other's throats. That makes it easier for them to rape the treasury and consolidate their power bases.
This won't be pretty, however it turns out.
