The US has a long history of "stochastic terrorism", which seems to be at a relative low compared to the violence of the early 1900s, the 1960s, and several other periods etc. I have faith in its institutional ability to handle and restrain actual violence.

I am much more concerned about the normalization of the idea that we should restrict free speech. I suppose this isn't too shocking - the Alien and Sedition Acts were passed after what we would now call many instances of "stochastic terrorism" in the newspapers - but I'd hoped we'd learned our lesson and permanently repudiated these ideas.

Because things were worse before doesn't mean we need to stop trying to be better in the future.

After January 6th, I don't share your assessment of the present or recent past. Free speech seems excessively protected today, even for veiled threats; moreso if one is rich or popular.

Unfortunately, discussing this too much more runs the risk of becoming too politicized for HN. I'll point out only that as deadly riots go, January 6 ranks at the near the bottom of American riots (lots tied with one fatality.) As protests or even attacks on or in government buildings go, it is not particularly notable. If that's what we're worried about, I'm not worried. It will be forgotten like the 50s Puerto Rican attack in the Capitol and it will have had less effect. If there'd been a stronger police response/presence as there was during the BLM White House protests or some earlier Capitol protests, you'd not even be hearing about it today. But for that accident (or conspiracy if you're so inclined, or deliberate underestimation of the threat of Trump supporters, or whatever) it would have been forgotten on January 7th.
