 The officer, whose department had been enlisted by the Secret Service to help with security, encountered the murderer who pointed his rifle at him. The officer then backed down the ladder. That's when Crooks immediately took aim and fired shots. I don't know why the officer wouldn't immediately point his gun and even at the very least duck behind, duck under the roof line and then point your gun over the roof line. I don't know why he wouldn't do that. I mean, I got questions about that.
