If he did both (remove the mag. & pull back the slide) why was there still a round in the gun?

Maybe the moron didn't pull the slide back far enough and with suffcient force to eject the round. He was more interested in 'show & tell" then a clear weapon.

Maybe he reinserted the magazine after clearing the chamber, but before releasing the slide.

If Lou Horuchi and Rick Brana still have jobs, this guy has nothing to worry about.
