I've been preaching the same thing for some years! If enough citizens engaged in misdemeanor civil disobedience, the politico elites might start getting the message. The TEA Parties were a good start.
Us Constitutionalists need to take it to the next level. Remember how the hippie protests/sit-ins/marches made us pull out of Vietnam? We could do the same regarding many issues. And with the more gentle DC and Park police, bloodied riots wouldn't happen in this day. Maybe a few may go to jail for failure to disperse or unlawful assembly, but that is a minor misdemeanor and has little affect on a person's record unless you're looking for a FBI, CIA, NSA, or other high security position.
You may think I'm just talking the talk. But some years back I volunteered to lead a group to chain themselves to the Capitol steps about illegal immigration. Sorry can't find the posts.
Not so sure on the illegal immigration protest. There’d be a counter protest at the same time which could turn bloody. Americans have to push the politicians to enforce the laws that are already on the books concerning people being in the US illegally. When Mexico protests US immigration laws tell them “sure, okay, we’ll use your laws on illegal immigration”.
