Antifa also likes to hide their faces too. Maybe there should be laws against all masked individuals who commit criminal acts. Y'now, if you are assaulting people with rocks and are wearing a mask not only do you get the charge for assault but also another criminal charge for being in disguise.
As GS mentioned many States do have some laws against the wearing of masks or not displaying your face but often these have caveats like in commission of a crime, in public demonstrations, etc.
The problem is enforcing the laws. We can write and pass laws all day long but if the police won't enforce them, DAs won't prosecute, mayors tell police to 'stand down,' juries won't convict, etc. I'm not sure what good they would do. As you mention we have laws against burning things in public, throwing rocks, bricks, frozen soda cans at police or people, and so on but still often the police usually let antifa, BLM, etc do their thing. I think the mayor of Baltimore even said something to the effect of "let them riot."
