Hoffa's Thinly Veiled Threat of Violence; Obama Silent

Just before Obama's Labor Day speech, Jimmy Hoffa threatened violence against millions of concerned citizens who think the government is too big. Naturally, Obama praised Hoffa and was totally silent about his call for violence.

So if we have another Giffords-style shooting, will the media call Hoffa and Obama the responsible parties? Or maybe this is what Obama considers using "words that heal, rather than words that wound?"
