 A local cop actually confronted the shooter on the roof and then had to retreat because the shooter swiveled the gun around. And then when the shooter swiveled the gun around, he went down the ladder up to the roof, the local cop. And at that point, he swiveled back around and started shooting at the president. According to the Associated Press, a local law enforcement officer climbed to the roof and found Crooks. That's the name of the shooter. Again, I normally don't mention the names of mass shooters or shooters on the show. This is an exception when you try to kill the president of the United States.
