I don't actually support any state-sanctioned murder/killing. None. If I joke about opening fire on these morons its because they would have launched a fucking drone strike if that crowd was even 10% BIPOC.
That said, the state disagrees with this perspective, and will kill you. I am at least smart enough to know that if I storm a Federal Building (especially the fucking Capitol?) and a plain clothesed internal Capitol Cop has a firearm drawn and is repeatedly warning me and I go ahead and proceed to break glass and break down a door, threatening him and what he's sworn to protect, I should expect to be killed for my cause. My empathy has limits, and ultimately the test is "play stupid games, win stupid prizes."
Even as an ardent leftist, personal responsibility is a real thing in the real world. You play, you pay.
