Corrected entry: After Riggs has beaten Joshua, Murtaugh is holding Riggs after he collapses. Riggs is facing away from the action of Joshua getting cuffed, yet reacts along with Murtaugh to shoot him, then collapses again. And where was Riggs' gun the whole time during the fight? It wasn't in his waistband where he always carried it, and no holster. It just conveniently reappears when needed.

Correction: First off, Riggs turned around because Murtaugh turned, and pulled his gun, Riggs would have easily known what was going on. Secondly, Murtaugh had Riggs' gun. Riggs just pulled it from Murtaugh.
