When, not if, push comes to shove you can count on 98%+ of law enforcement officers defaulting to their paycheck when given the alternative of enforcing unconstitutional, tyrannical orders or being unemployed.
That is because 98% of cops don't
really think their job is going to kill them, so they default to paycheck.
If the choice is paycheck and 50% (or higher) chance of dying, or live and find a new job, I suspect a bunch will choose alive and unemployed.
Solzhenitsyn touched on the fact, and we need to realize the fact, that if there's actually tyranny that we need to fight, we need to kill the agents enforcing it. Not if they kick in your door at 3 am, that's too late. When they are writing tickets, drinking coffee, or pumping gas.
