What Komenich did was not necessary smart, unless of course, like him, you are several inches taller, more than few pounds heavier and quite a bit stronger than the crook. At my height, a better bet might have been to bop the critter on the head with a heavy camera.
Nevertheless, three cheers for the hero photographer in this story, but lucky for him the intrepid robber didn't have a weapon. Otherwise, the ending might not be one for pats on the back and congratulations.
