“it looks like a very unsavory bunch did a circular firing squad on themselves.”
If that were the case, the DA et al would have been quick to hold a news conference touting that line and trotting out supporting evidence - that’s what usually happens in most cases in most places.
That the DA et al have, instead, clammed up and are saying as little as possible - and what they are saying is profoundly stupid - is putting this story squarely in the implied “other” category opposing your “most of the latest” comment. Isn’t helping that their behavior strongly resembles notable police/legal behaviors in the same city some 22 years ago - an event which was hardly “fiction”.
Their reluctance to release even the names of the dead bikers makes me wonder if they didn't screw up and shoot one of their own.
