 There's FBI interrogation going on right now, investigation, interrogation of the local law enforcement officer who peered up on the roof. Now, initial reports, people were saying, oh, my gosh, how could he not engage the shooter? There's already some pushback to say that he pulled himself up to see and the sniper who had plenty of time to prepare. Some say they looked and 30 minutes before they recognized there were somebody on that rooftop, other Secret Service.
