Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Government adopts and enforces many measures that are designed to further a valid interest but that may restrict freedom of expression. As an employer, government is interested in attaining and maintaining full production from its employees in a harmonious environment. As enforcer of the democratic method of carrying out the selection of public officials, it is interested in outlawing
corrupt practices and promoting a fair and smoothly functioning electoral process. As regulator of economic affairs, its interests are extensive. As educator, it desires to impart knowledge and training to the young with as little distraction as possible. All these interests may be achieved with some restriction upon expression, but, if the regulation goes too far, then it will violate the First Amendment. 1
