“People who are saying helicopters did all the shooting… forgot about the noise that helicopters make.” – Jeff Rense on the Jeff Rense Show, 11/22/17
For example, the cabby footage and other videos have clear sounding footage from a nearby shooter, but there is no helicopter sound at all.
Even the lower noise copters can be heard from about 1/2 mile away, Gary Holland points out. I found them annoying, when I visited Vegas.
