” Clearly some of the bikers are guilty of nothing but being in the wrong place at the wrong time.”
LOL!
Show up for a gang fight armed to the teeth and you just happen to be in the wrong place at the wrong time ...
It's nice to be the Blue Gang. All the other gangs are afraid to shoot at your gang members - and you get to hose the place down with lead indiscriminately...
From media accounts it seems likely that a fight broke out between rival gang members that accelerated into a gun fight when someone opened fire. The local police (who were already there in mass) then opened fire on the gang members. Many people who were charged were not armed and did nothing more than duck for cover when the shooting started.
Of course, I was not there. I always start from the assumption that most of what the lamestream media prints about anything is at best distorted or at worst outright lies. So there is no telling what really happened until there is at least one trial.
