CONFIRMED!!! 2 separate and distinct rifles in Vegas Shooting

A Vegas cab driver video confirms without question that there are separate and distinct rifle fire during the night of the  LasVegas mass murder. Key point in video - 44sec and 1:08 , notice different locations of gunfire. Additionally at approximately 4:58 there is noticeable muzzle flash coming from a few stories up of the Mandalay Bay Hotel, not the 32nd floor.  Some have indicated that flash could have been a strobe reflection. Could it have been a muzzle flash reflection from another location? 

Still yet the most important aspect of the video is the beginning with the very noticeable different locations of gunfire.
