Seemingly wherever they go the Minuteman Project is met by violent, far-left protesters who have rather curious interpretations of the First Amendment. The latest example comes from Chicago, where five protesters were arrested for assaulting cops outside a MMP meeting in Arlington Heights.

The Tribune:

...About 120 police officers with riot gear and police dogs were summoned from other suburbs to restore order.

The protesters arrested were part of a group that included dozens who identified themselves as members of socialist, anarchist and anti-war groups...

But Arlington Heights Police Sgt. Richard Marcinkowski said some Minutemen participants escalated the situation by coming outside to debate protestors.

"We had two unreasonable factions," Marcinkowski said, "and we got caught in the middle."

A second counter-protest of about 300 immigrant advocates also materialized and briefly joined the first protest of leftist activists.

Police said the second group, organized by the Coalition of African, Asian, European and Latino Immigrants of Illinois, had nothing to do with the violence or disruptions...

The Sun-Times report doesn't go in to the ideologies of the protesters.

There are several links about this here, and pictures are here. A sample from the last link:

It didn't take too long before protesters decided the resistance to this group needed to be more spirited. Some youth started dancing in front of the entranceway making it difficult for the Minutemen to pass in an out. There were drums and chants. Then officials of the conference started getting, well annoyed would be one way to put it. But we were also annoyed that we have to live in a world where such groups like this exist.

At a certain point people turned from dancing to being more determined to stop the Minutemen from entering this conference or letting this conference just go down. Protesters linked arms as the police tried to drag people away. And Minutemen organizers were trying to argue down the protestors and failing. The police tried to push, pull and pry the protesters form this entrance way but failed. A great cheer went up as the protesters stood firm and blocked the way.

UPDATE: There are pictures and a report from one of the MMP volunteers here. And, note that the World Can't Wait folks appear to be active in other areas; see this.

UPDATE 2: I should have seen this coming. One of the spokeswomen and "initiators" of World Can't Wait is Sunsara Taylor, who's also a supporter of the... Revolutionary Communist Party. As pointed out at DK, their domain name is registered to Clark Kissinger, another "initiator" of WCW. Among many other highlights of his resume (dissident.info) is this: "Supported Bob Avakian's work to build a real communist party in the U.S." For a link to something MMP-specific, see rwor.org/a/019/debra-sweet-world-cant-wait.htm . Everyone should ask the Sun-Times why they didn't discuss this in their article.
