Valle is a paid Soros activist who explicitly set out to achieve what you saw on video and those there were stupid to take the bait.
So that's what really happened. Generally the liberal leftist media wants to see full video so as to set context...except when that defeats the narrative they're trying set up.
The fact that conservatives condemned Tim Proffit sticking his foot on Valle’s shoulder shows, again, that the right polices their side. The left does not. They create standards that they expect everyone else to follow; I’ve still yet to see a single one of them condemn the attack of Kelly Owens, on camera by SEIU, Kenneth Gladney, Alle Bautsch, Bill Rice, John McCormack, the assault on NC tea partiers, I could go on. The left has yet to rise to the challenge and match the right in condemning violence such as the examples I’ve given here.Basically, the message the media is touting is that it's perfectly ok for liberals to assault political opponents with impunity, while anyone on the right is used to smear both the Tea Party movement and the GOP/Conservatives. Democratic/Liberal hypocrisy in action.
UPDATE: What people often forget and what has become the 20th Century's big lie...Adolf Hitler was a socialist, as was Benito Mussolini. Adolf's Brown Shirts, and Benito's Black Shirts did just the sort of thuggery that is becoming common from the supporters of the Democratic Party today. The SEIU has become the "strongarm bullies" of the Dem's and have assaulted conservative protestors in pretty much every part of the country. This is what the NAZIs and Fascists did in the 1920's and 1930's.
