The previous prosecutor screwed this up so badly, cost innocent people their livelihoods, failed to file charges in anything like a timely manner and overall just fucked up. The result of the previous prosecutor not doing his job correctly lead directly to this new prosecutors actions. Keep in mind, these MC's/Bike clubs have a strong no snitching code that hampers prosecution. "Nobody saw nothing." Can't prove who held what weapon so can't pin any killing on any individual...this was a cluster fuck from the beginning and the law suits flowing from those inappropriately arrested (there were 177 arrested but only a handful were actually involved). Businesses were lost, careers hampered and damage to reputations were profound. Most of the folks at the Twin Peaks were from other Motorcycle Clubs just enjoying an MC meetup and not in any way involved, but they were arrested and many charged none-the-less. Had the previous prosecutor not sought to indict so many, he could have indicted those directly involved in the Bandidos and Cossacks and worked out those cases. But instead he chose to dilute the the actual indictments with folks who never should have been charged. This latest announcement is a direct result of the previous prosecutors failures. This is not a conspiracy by republicans to not arrest folks, this was a failure of the Waco district attorney Abel Reyna and his office, nothing more.
The meeting between the cossacks and the bandidos was a side bar that just happened to take place at the Waco Twin Peaks when other MC's were also gathering to meet and eat.
