I won't even take a gun from a clerk without an open slide. And I don't think I've ever had one try to give me one without an open slide.
But that officer made too many assumptions He racked the slide in the correct manner but wasn't paying attention at all. The responsibility lies with the one handling the weapon, but he'll get some money out of this.
Lots of good replies, but this is the best. The person handling the weapon during the negligent discharge is at fault.
