Meaning, you should understand, not a gun you hold in your hand, but rather, the hand itself, thumb cocked and index finger extended to resemble a pistol. One afternoon late last month, Entingh, who goes to school in Columbus, Ohio, was goofing off in science class when he raised such a "hand gun," pointed it at another kid's head, and said, "Boom." Not a good thing to do and Entingh, who is 10, should certainly have been reprimanded. Instead, he was suspended for three days. His father, Paul, says he's been told that if it happens again, the next suspension may be permanent.
