Why do the authorities allow Alex Jones to broadcast on the Internet?

Free speech was designed for news, weather, sports, fashion and trivial matters. To allow rock-solid truths to be spouted like a 24/7 gushing well seems to me a little risky. Shouldn’t the authorities shield us from reality? What if we panic and empty the store shelves of food? Why is Alex Jones allowed to live and communicate?

It’s this little thing we call the Constitution of the United States, read the first amendment it will answer your question.
