Are the American people now considered collateral damage?
Yes...no one person stockpiles that many weapons and ammunition to shoot up anyplace. It could be that Paddock went up there to stop the shooters or was a patsy who needed to pay off his debt to the casino! My money is that this was an ISIS op to kill most of the people in the casino and the whole concert thing was collateral after someone interfered with their plan. The Saudi prince angle is also interesting, although no one would stockpile weapons for a hit.
