Interesting article which covers several confrontations since November 2013 between the two groups. Also interesting bit:
"The incident erupted in Waco, according to the documents, after the meeting of the Region 1 Confederation of Clubs and Independents was moved from Austin to the Twin Peaks in Waco. Nearly all of the recent Region 1 COC&I meetings had been held in Austin, and it is not common for members of any of the other 11 COC&I regions in Texas to attend a regional meeting of another area of the Texas COC&I, the affidavits say. Many of the 177 bikers arrested in the Twin Peaks shootout were from outside Region 1.
The Cossacks are not members of the local COC&I and the Bandidos are. However, the Cossacks consider Waco “their territory and made the decision to take a stand and attend the meeting uninvited,” according to the court documents.
“Cossacks threatened that Waco was a ‘Cossacks town’ and nobody else could ride there,” the records state. “The large number of Bandidos and their supporters showed up to the Region 1 COC&I meeting because the Bandidos wanted to have a show of force and make a statement that Waco was not the Cossacks’ town.” "
So, it looks like this wasn’t a pre-arranged meeting of the groups as initially reported. The majority of folks there to attend the Region 1 meeting wouldn’t have expected the non-member Cossacks to be there with the potential for a confrontation (folks like the veteran’s riding group, the Christian riding group etc.)
It also indicates how many innocent folks could have been swept up since they would have been arriving for a 1PM meeting, while many of the Cossacks arrived much earlier.
However, if the police had any informants associated with the group, they would have been aware of the potential for a confrontation, and violence, and explains why they were present in fairly large numbers despite many previous biker gatherings there never having had any violence.
Also, the you can see many, if not all, of the folks who had vehicles confiscated had criminal records . ETA: Note, many of the descriptions refer to actions caught on video during the shooting.
It will be very interesting once all the information is released— if ever.
