A personal story on Vegas Concert so it doesn't get lost **was deleted by Facebook** #DNN

Not to feed into conspiracy theories but, can someone who knows more about guns than me explain what is heard at approx the 2:00 mark? Sounds like 2 different guns from two locations.

Seems more feasible that: As he sweeps the fire across the area to the point where the camera is being held, the crack of bullets become more pronounced? As the fire continues past the camera you no longer hear the cracking of the bullets passing through the air. Perhaps some of you have heard this phenomenon and can confirm?
