This is the opinion piece written by Harel Shapira.

I've taken a few gun classes and like David Yamane I've never heard what Shapira says he was told in classes. On the contrary, instructors always stressed caution. I'm sure Shapira's version reinforced NY Times readers belief that concealed carriers are crazy and shouldn't have guns. With his article and forthcoming book, Shapira seems to be whoring for anti-gun bucks.
