 A source with direct knowledge of the incident says three snipers from local law enforcement were staged within the building just beneath the shooter. They observed Crooks acting suspiciously before the shooting and radioed into command that he was using a rangefinder and had a backpack. By the time help arrived, it was too late. We're told neither local police nor the Secret Service checked the roof before the rally. One death just confirmed after tornadoes swept the Midwest overnight.
