““Repeatedly courts turned to the First Amendment. The right to speak is fundamental, but is limited or regulated under myriad circumstances. You are not entitled to commit libel, or to turn up a sound truck to eleven at three in the morning. As Justice Holmes wrote, you cannot falsely shout fire in a crowded theater. The First Amendment does not enable you to stage a parade without a permit: government cannot ban your political speech, but can set rules on “time, place and manner.” Courts treat campaign contributions to lawmakers as a form of speech, but have upheld limits on the size of the gift in an effort to ward off corruption.””
