“No one knows for sure how and why the shooting started, or at least the reports have not been vetted in discovery, court, etc.”
Every account that has come out has said it started as a conflict between the two groups of outlaw biker gangs out in the parking lot. Sure, you can hem and haw about that not being confirmed in court, but the fact remains, there are no competing accounts of how the event started, except the musings of people on the internet who weren’t there.
No doubt, it’s compelling to form an opinion and take sides early. But if we have learned anything in these days, it is that the media and even law enforcement can heavily skew initial impressions away from the actual events.
