If you don't know the names and affiliations and histories of the deceased, then you are being presumptuous--unless you consider everyone on a motorcycle a "thug", in which case you fall into a different category.
If you have more information on this event than has been forthcoming from sources seen so far, such as identities of the deceased and their criminal records, kindly provide a link, or if you have first hand knowledge, share it.
Yeah, everyone wearing a “Bandido” or “Cossack” jacket, I regard as a criminal thug. Good riddance to ‘em. I don’t care where the bullets came from.
One report stated 1 Bandido deceased, 8 Cossacks deceased.
The beef was that the Cossacks were moving into Bandido territory, plus wearing the Texas rocker and giving the finger in a photo of them wearing the rockers.
