Good pick, IMO

it turns out if you are all able to stop work at once (and discourage scabs from crossing your picket line) you have power, whether or not you’re an employee on paper.

But it does highlight that any random brute could put on a mask and do this with no authorization whatsoever. It’s a fundamental human-rights and rule-of-law breakdown to fail to present a warrant. I agree that a warrant doesn’t ethically make the arrests anything short of monstrous, though. That kind of legalist can suck eggs.
