Whackos in Waco

Slate has an article by Ben Mathis-Lilley about some out-of-control (as if there's any other kind) bikers in Waco, Texas:

Update, 1:55 p.m.: Twin Peaks' corporate has revoked the franchise rights of the Waco restaurant where the shootout took place, writing that the outlet ignored "warnings and advice from both the police and our company" that its cultivation of gang-affiliated bikers as patrons was creating a security problem. The Texas Alcoholic Beverage Commission had already ordered the restaurant, which was scheduled to hold a bikini contest on Wednesday, shut down for seven days.
Original post, 12:43 p.m.: Police estimated that they arrested a staggering hundred and severty-five individuals in the wake of a shootout among motorcycle gangs that left nine dead and eighteen injured at a Waco, Texas, shopping complex, officials said. The violence began Sunday about noon, and suspects were still being booked as of Monday morning.
The incident began at and took place in and around an outlet of a breast-themed establishment called Twin Peaks, which is reportedly the fastest-growing restaurant chain in the United States. A spokesman for Twin Peaks says the company is “seriously considering” revoking the franchise rights of the Waco restaurant, which was reportedly uncooperative with local authorities who had become concerned before Sunday’s shootout that it was becoming a gathering place for gangs.
“There is blood everywhere,” a Waco police spokesman said of the crime scene.
A number of motorcycle clubs were reportedly represented at the gathering that turned violent, but the individuals who died reportedly came from two groups, the Bandidos and the Cossacks. Per an excellent Washington Post piece on the Bandidos and other criminal motorcycle gangs, the Bandidos are known for trafficking drugs (especially methamphetamine) and were founded in 1966 in Houston, Texas. Affiliated Bandidos groups have been involved in large-scale deadly conflicts as far afield as Canada, Australia, and Scandinavia. A Kansas City-area police officer named Steve Cook says that even members of law enforcement are known to let the romanticized image of outlaw bikers in popular culture undermine their understanding of the threat such gangs pose: 

“They watch their Sons of Anarchy and other television shows. These guys all seem likable enough: that they are misunderstood, outlaws from the old days, and they ride motorcycles instead of horses,” he said. “Even cops think: ‘Oh, they're just tattooed long-haired guys who like to ride motorcycles.’ And the reality of it is, they are long-haired tattooed guys who ride motorcycles and sell a hell of a lot of methamphetamine and murder people and steal motorcycles and extort people and beat people up in bars for no reasons.”

Less seems to be known about the Cossacks than the Bandidos; a source in the Post’s piece suggests that the Waco violence may have been precipitated by a potentially threatening alliance between the Cossacks and the Hells Angels, a major Bandidos rival. The Associated Press notes that “a 46-year-old from Abilene, Texas, who police say was the leader of a West Texas Bandidos chapter” was accused in November of 2013 of stabbing two members of the Cossacks in El Paso, Texas.
Signs for a nearby Bed Bath & Beyond store can be seen in CNN’s images of the Waco crime scene. In a further bit of surreal incongruousness, the Department of Justice refers to criminal biker gangs as Outlaw Motorcycle Gangs, or OMGs.
