Shepard’s related article and the video discussed here:

SHOCK FOOTAGE: Helicopter caught hovering, lurking, behind the Delano Hotel as Las Vegas Shooting ensued

39:00 Supposed Luxor shooting video could not have been gunfire: “…the police helicopter in this footage had to be taken after 10:23 pm. … That’s what a police helicopter looks like…. But these other helicopters are lurking behind this thing.” – Shepard Ambellas
Comments I wrote under the video:

Machine gun fire was *NOT BLANKS: Joe Napoli: “You could hear the bullets hitting the metal seats of the bleachers* . At that point, the third burst of bullets, *I thought that I was going to die”*

(vid) Walking in the Footsteps of Vegas Survivor Joe Napoli — “I saw casings right here …  a dozen, brass, 1.5-2″ tubes spread out” • “You could hear the bullets hitting the metal seats of the bleachers [they were hiding under]. At that point, the third burst of bullets, I thought that I was going to die”  

There were massive gunshot casualties. Two days later, one hospital still had 59 gunshot wound patients being treated:

(vid) Surgeon at Vegas hospital that treated 200 reacts 2 days later: “We currently have 59 patients, gunshot wounds, still in the hospital, 31 still in critical condition” • 2/3rds were gunshot wounds 

Full metal jacket (FMJ) bullets do NOT “cut people in half.” They often leave tiny holes, because they don’t expand like many single shot bullets.

PHOTOS: AR-15 Bullet Holes are Tiny – Thinner than a pencil – Not easily seen from a distance 

Oasis video proves the last volley was NOT fired from a helicopter, because the gun sounds were so clear (shooter nearby), yet no sound of helicopters at all. Bus stop, taxi cab, and other videos show this too.
