How is this violence happening?

This comes out on the heels of the lady getting stomped at the Rand Paul rally, and a reporter getting handcuffed and detained by Joe Miller’s private security forces. Let us not forget the bricks through the windows and other violent acts back when the Healthcare bill was passed, the spitting and name calling at/of congressmen and women back around that time, or the passionately disrupted town hall meetings of last summer.

Here’s my question. What, if anything, has our justice department done behind any of this? Is this violence protected speech? Is lack of prosecution only allowing it to continue and, probably, escalate? When did one man’s free speech become his violently prohibiting another man’s free speech? We are becoming a very intolerant nation, and the bullies are running the country. Funny: the entire nation wants to address the problem of bullying in school, but bullying in politics is accepted. Almost seems like a good career choice.
