Could I see the cops shooting patched members? Yes. That's believable. If deadly force (includes hammers and blunt objects) is being used in the melee in the public restaurant, that can easily be forseen.
Could I see outlaw MC's trying to pin this on the police? Yes. Takes off some of the heat.
I think the dead were in the parking lot
Not inside
I could be wrong
Info is not forthcoming which usually means CYA
From what I’ve gleaned from the news is that only a few were the primary combatants. A police spokesman said that there were members of other clubs who weren’t involved. Police were on the scene because they expected trouble and say they didn’t fire till fired upon directly because they knew that many were non combatants.
