As long as LE allows the democong and the Deep State to dictate which groups are allowed to riot, to assault political opponents, and to assassinate cops with impunity...cough cough, OWS, antifa, BLM, cough, cough...then bags of filth will continue to be thrown at police. They are victims of their own refusal to defend the citizens.

The common defense is listed in the Constitution as a primary task, and Madison makes a point of defining the defense of the citizen and his property the highest priority of the Constitution and of government.

No law, regulation, or political decision that abandons that duty is lawful. PERIOD

I made the case for the complete rollup of the democong under RICO law in an earlier post.

As soon as the line cop, and/or the line serviceman, steps up and fulfills his oath, this country will be more prosperous and more secure...in addition, it can be done lawfully, and bypass the need for American citizens, who have been repeatedly betrayed, to take matters into their own hands.
