One of Rolling Stone's reporters decided to look into the FSU and the murder of James Morrison which took place in January of this year. In the ensuing weeks, rumours of FSU involvement and speculation about racial undercurrents caused much speculation about the nature of the crime and the motivations of the perpetrators. Most notably, it drew national attention to the infamous hardcore "crew," the FSU.
The article, titled Punk Rock Fight Club: The Gang Behind the Mosh-Pit Killings was written by Mark Binelli and runs nine pages in the magazine. Unfortunately, the article itself is not available online, but a 3 minute, narrated "slideshow" does discuss some of the more pertinent issues. Also mentioned are some of the other crews as well as the controversial Boston Beatdown series.
