My theory is that this was originally planned to be a false flag event to kill rap fans and cause a race riot. When that didn’t pan out, it changed into a plan to kill country music fans.
I just posted the same thing on another thread.
Plan A was false flag op - “right wing extremist shoots up diverse crowd”. BUT, if they/he got caught, it would be found to be false flag and have the opposite of the desired affect.
Plan B - just shoot up some conservative knuckle draggers - they deserve it anyway.
