There’s a very broad range of plausible arguments about how to read American law. Saying “my interpretation is that this violates the First Amendment” or “I think the better reading is that obstruction of an official proceeding requires violence or perjury” are not lies, even if they are bad arguments.
But some people are absolutely lying to you about the law and how it applies to the indictment of Donald Trump — or, at the most charitable, Cliff Clavening it by speaking confidently from a place of deliberate ignorance.
You can tell which ones are lying to you when you check their sources. And if they don’t offer any, you shouldn’t trust what they’re saying.
