There was rioting in many major cities and it was absolutely appropriate to call in the national guard to put a stop to it. My family didn’t leave Bangladesh to put up with third-world behavior like that.
Protest isn't third-world behavior, and part of being in the US is not restricting other people's liberties - regardless of your personal preferences and outrage.
If they are harming others or causing significant material damage, that's another story, but even that is a matter of degree (especially the latter).
