I’ve looked at the cab videos, heard the dispatcher feeds, seen the various references to strobes, looked at the various other posts and evaluated reports from observers.
I think you have gone down a false trail of this investigation.
Possibly. Pursue all info as if it’s real til you cN completely disqualify it.
I only know one thing: whatever that light is, it’s no strobe. The strobe is clearly visible in another shot, and is NOT synched to the sound of gunfire.
