The Las Vegas Police and the FBI can find no reason for the mass shooting that occurred there on oct. 1st 2017....well over a year ago. Sincethey can't find a reason for that shooting, I guess it's asking too much for a reason for the largest mass shooting EVER in the USA, 129 years ago, which happened Dec.29th, 1890 at Wounded Knee Creek at the Pine Ridge Indian Reservation.
