Maybe, but a sonic weapon using Ultrasound and infrasound hidden in it does the same. meaning you can kill someone just as assuredly as using a gun and TI's being hit Targeted people being hit if you set a glass of water on a table it will slosh around. One can make gunfire sounds hidden in an Ultrasonic sound wave along with Infrasound in it and I think the gun in the barrel as you say is this killing people using sound. But why does that point to Iran? A gun being shot into a barrel doesn't signify Iran to me but it could be?

Amen Jennifer. I tried to post back but lo and behold me send is gone
