4. Why did the cop who engaged the
shooter not use his weapon?
A law enforcement expert joined "Fox News @ Night" on Sunday to detail what happened when an officer at former President Trump's Pennsylvania rally allegedly confronted the gunman on a rooftop before the deadly shooting on Saturday.
Retired Las Vegas Police Lt. Randy Sutton says the officer was alerted to the gunman, now identified as 20-year-old
Thomas Matthew Crooks, and was attempting to confront him on the roof, but there was "no ladder" or access point.
The officer decided to reach Crooks by climbing onto the back of another officer, according to Sutton's sources.
"As he was lifting himself up over the roof line, suddenly the suspect pointed his gun at him, the officer ducked down, and when he did, he fell off the back of the other officer," Sutton said.
Sutton explained that this was not a situation where an officer committed a "cowardly act," dismantling an earlier report that the officer possibly retreated when he confronted Crooks.
"This is an officer who made an observation, saw that he was about to be shot, and fell off the back of the other officer," Sutton said.
