In a strange way if true it reminds me of the Police response to the Columbine High School crisis . Police waited until the shooting had stopped before entering the School . Many students and teachers bled to death during that rather lengthy hesitation by Police. In Vegas "IF" the timeline of the Hotel Proves to be the " real timeline " then Police did not intervene in the Shooters bloodbath . They waited until he had already taken his own life to move on him . They could have drawn the shooteres attention away from his evil task in many ways ..thereby allowing the Festival goers a more secure escape . We can only hope that this timeline is in some way incorrect because if true and accurate Vegas Police become almost complacent in this act at the Civilians expense. I cannot believe they would allow such a horror to just unfold without some kind of intervention  or prevention .At the very least draw the Shooters attention away from his task to save Civilian lives ..
