Just tossing the First Amendment out the window, at the current time, would not have the support of the courts. It would be declared illegal in no time. It would then require using the power of the office to suppress free speech by force - literally having police or military shut down radio stations, TV stations, newspapers, and the internet (don't forget cell networks and ham radios). The military is unlikely to undividedly follow such a course. Now you very likely have a civil war.
