"Some seem to have forgotten that the First Amendment to the United States Constitution guarantees the “right of the people peaceably to assemble, and to petition the Government for a redress of grievances.” That is the authorized way to raise public awareness and to focus on injustices in the content or administration of the laws...

That is anarchy, a condition that has no effective governance and no formal police, which undermines rather than protects individual rights.
