investigators believe the shooting was triggered by a personal dispute between a small group, and the parade was not the target.

Were any of the thugs involved in the "personal dispute" hit by any of the gunfire, or was everyone hit some random parade-goer? If thugs insist on shooting their ops, it'd be great if they got in some range time to work on their aim.

one of the guys who was shot claimed one perp raised the gun and then just spun in a circle trying to shoot as many people as possible

so it is more than just a gang dispute.
