Rational thinking from Aristotle no less led people to believe sheep heads were full of flies.     EASY SHOT LITTLE RISK. I can't think of anywhere in the world where a large gathering like this doesn't come with police or military armed with an AK47 or M-16.   Anywhere in the world the shooter would have been fired upon. And guess what? The Las Vegas Police shooter squad was off duty, attending the concert.  I think your prejudice clouds your rational thinking. Your rational thinking leads to dead people and a nation of sheep.  And where do you come off thinking trained security guards are better shots than civilians?  Do you think all ex military people go into law enforcement? Darn few do. I fixed radios in Vietnam and wore my Expert tag.  My best friend was a USMC sniper and became an electrician who eventually ran his own company, Another, was a F4 Jock, has The AF DSC and 4 silver stars 5 purple hearts and more.  He came back to be a successful Financial Advisor. So.
