Shots fired at least 10 injured at Chiefs Super Bowl Parade

Asking a legit question, not making a political statement…

Hearing that this was a dispute between 2 or 3 parties. Was this a pre planned mass shooting, or was this a result of stray bullets being fired needlessly?

Yes, I know, either case doesn’t matter based on the outcome, But I am hearing/reading mixed motives.
i doubt it was a planned shooting. If i had to guess some punks got into a fight and decided to start shooting at each other..
