From my above linked article:
“A Brenham couple and about three dozen other bikers arrested after the deadly melee at the Twin Peaks restaurant in Waco last May may avoid prosecution.”
“Of those who are not facing charges so far, none was a member of the Bandidos or Cossacks. All were in the vicinity of Twin Peaks for a regional motorcycle club meeting that was supposed to be about safety and changes in the law.”
So, about 40 people were arrested and charged with murder that weren’t in a gang, just happened to be at a motorcycle gathering. And the cops just blanket-arrested everyone around.
I believe that all were in gangs.
