What shooter? What second shooter?

My friends dog just jumped over a fence and has more blood on him than I saw total at Vegas - it was a play - a TV show - that is why there is no REAL panic, or cops, or security, or paramedics, or PEOPLE RUNNING AWAY! Real concert + bad actors + compliant peripheral support = Massacre: made for TV special.

The video explaining the acoustics is because the shooting sound was coming from the speakers - as many eyewitnesses reported.
