If you are a good shot you don't HAVE to limit yourself to broadside shots. I see absolutely nothing wrong with shooting a calm deer facing you at 30 yds. with a gun. With a bow, it's a different story. But there is nothing wrong with the shot he took....only the fact he didn't make a good hit. It's easier to hit the vitals on a 30 yd. frontal shot than on a 100 yd. broadside simply due to the range.

I think he did all he could do. It sucks, but I bet he learned from it.
