Could the image itself be a photoshop
If you notice though, it is barely in the magazine well so the "highly trained" officer actually could have got it in backward I suppose. No way as I remember to really seat a magazine very far in facing backward. Hell, I can remember training ambush situations (on the surprise receiving end) where I fired multiple magazines in reaction without even
consciously changing the magazines. And they all went in the right way. Shows why you train until some things are instinct.
