Charles Johnson will forever live in Blogging infamy for having a nervous breakdown. Along with Andrew Sullivan, he turned on everything he once stood for and joined the Left. Then he became obsessed with mocking and smearing the Right. David Frum now joins the nervous breakdown club. He goes on a Twitter rant mocking the idea of armed guards in schools.

David Frum’s rant ranks right alongside Charles Johnson’s 32 Rand Paul posts in 5 days back in 2010 as a clear case of a mental breakdown.
