"You raise your voice, I erase your voice.” This viral video of an ICE agent threatening to silence a Minnesota protester is about as un-American as it gets. The events in Minnesota give the country a lesson in the First Amendment that we’d all be better off remembering: The government can punish actual crimes, but it cannot punish protected criticism or protest. When the government blurs those lines, it stops enforcing the law and starts acting like might makes right. That should scare every American.
