Prosecutors have charged and prosecuted multiple members of urban street gangs such as the Crips and Bloods for one murder.
No reason why the biker gangs should be treated any different.
There were at least 5 motorcycle clubs there, not all of them identified as gangs or organized crime, and many unaffiliated riders.
Saying they are all “crips or bloods” is dishonest.
Saying the restaurant is culpable is like saying that the Kmart/Sonic Drive-In that was “home” late night street racing was likewise culpable for organized criminal activity. Police raided the parking lot picking up teens out after curfew and others who were guilty of numerous criminal offenses (merely those in the parking lot, not the business owners) and the city of Houston had the book thrown at it for “abuse of power”. Pays to be a minority, I guess.
