When Karen and I were in Israel we were comforted by the presence everywhere of Jews with guns. Karen’s brother David, an accomplished lawyer, Rabbi and businessman, carries his Glock nearly everywhere.
David is a good man. Thus, he is a good man with a gun.
The reason he carries a gun—and is licensed to do so in the Jewish state—is because there are millions of bad men and women, IslamoNazis, who seek to kill every Jew in Israel, every Jew on the face of the earth.
The only defense against a bad man with a weapon—any weapon—is a good man with a weapon.
