The defeat of gun control legislation in the U-S House recently came as no suprise to gun policy expert Tom Diaz. In his new book Making a Killing: The Business of Guns in America, Diaz says a better strategy would be to challenge gun manufacturers on their marketing of increasingly deadlier products. Diaz comes to gun policy from the perspective of someone who loved guns. From his boyhood scouting experience in Mississippi, to his military service, to collecting guns as an adult, Diaz says there were always guns in his life. Then his law degree landed him a job with the House Crime subcommittee.
