Looks to me like the officer engaged from the left side of one pillar away. the killer charged the officer while the officer was switching to the right side of the pillar and caught him looking the wrong way. Shot him in the back.
Saw this...over and over...on CNN last night.
Shot by a man who was horrified at what he called the “execution style” shooting of a police officer by a man who, as he also said, was obviously wearing body armor.
The guy who shot the video (think his name was Ismael Bejesus—sp?) said he was on the patio of his hotel room when all this hell started breaking loose, and he caught it on video in real time.
He will certainly be of value as an eye witness, because his narration of what happened revealed info that is not all that clear on the video.
