I have seen the Muslim Student’s Union in Action and they are a group of Brown-Shirts.

The event Awlaki attended was a September 9, 2001, benefit dinner for Jamil Al-Amin, at the Muslim Students Union of the University of California, Irvine. Also attending the event were Muzammil Siddiqi, then-President of ISNA, who worked for the Muslim World League during the 1970s. Both Siddiqui and Awlaki had lectured in separate panels at ISNA’s national convention near Chicago just days earlier (click for video).
