Lets see Mclaine was a good cop and a great character but Riggs was a psychotic cop who was unpredictable a marksman, an expert hand to hand fighter and legendary character and lets not forget he knew how to let people know he was pissed example pulling down their house and killing them all can't reaaly make your point much clearer then that
EDIT: Wait Riggs was a cross between Sledge Hammer and a suicidal maniac
