The whole thing seems weird. The scenario given leads a lot to what really happened. We don’t know what the police on the ground were being told to do or not do.
The information given to the public seems sketchy, at best. I’m just saying, I wouldn’t be in such a rush to judge the officers on the scene, because we just don’t know.
Police were told that the shooter was on the "32nd floor, room 135.” This police coward stayed on the 31st floor for 4 1/2 minutes while he heard the shooting going on from above. He should be immediately fired.
