Why Aren't Violent La Raza Protests News?

The press is constantly warning us about how the TEA partiers are this close to snapping and going all violent...while ignoring actual violent protests by leftwing groups and, in this case, a group (supported by Sonia Sotomayor, by the way) that supports "taking back" the southwest for Mexico (Wizbang for the tip since I didn't see it in the newspapers)

SEATTLE – More than 100 demonstrators demanding that that Pres. Obama pass immigration reform blocked off Seattle streets as well as people inside an office building. And they say they're prepared to do it again, soon.

The group started the day outside the Federal Building, but surprised some by moving into a building that houses an Immigration and Customs Enforcement agency office and court.

The group, including Seattle City Councilman Larry Gossett and El Centro de la Raza Executive Director Estela Ortega, locked arms during the noon hour and blocked the elevators. When some people tried to get through the human blockade, they were pushed away...

The rally included a coalition of groups organized by the OneAmerica organization. Group leaders say they will conduct another demonstration in a couple of weeks. They say it will have an element of surprise and will be an escalation of what happened Thursday.

Hmmmm...a leftwing group pushing for...I dunno, open borders or amnesty or something for illegal aliens...has already organized one violent protest at a federal office and is openly threatening more, not to mention an "escalation". Seems like the sort of thing that law enforcement should be looking into...except Obama's team is more worried about veterans and pro-lifers and old ladies at TEA parties to be wasting time on groups assaulting people at federal offices.

I know I don't even have to ask...but if a TEA party group had gone to an IRS office, blockaded it, and assaulted people trying to pass them do you think this would have made the news?
