The Las Vegas shooting timeline has been conclusively established to within approximately one second for the emergency Police scanner audio, LVMPD body-cam footage and shots fired.

LVMPD and the FBI are wrong, the first volley of shots took place at 10:06:05 PM , not 10:05.

Shot volleys end at 10:15:20. LVMPD/FBI maintain that no more shooting happened after that. But the police emergency scanner audio at 10:19:57 broadcasted that an LVMPD officer - call sign "765" - took over the channel to announce that he and others were still taking fire.
