Though many people might agree with blind musician Stevie Wonder that it is "crazy" to let people like him carry guns, federal and state laws seem ambiguous, according to a lengthy analysis of Iowa's supplied by the Des Moines Register in September. Some Iowa sheriffs believe that federal anti-discrimination law limits their discretion (though they can deny permits for lack of physical or mental ability to handle guns). The National Federation of the Blind generally trusts its members to never use guns recklessly, a spokesman said, and blind Iowa activist Michael Barber emphasized his right. "[Y]ou take it out and point and shoot," he said, "and I don't necessarily think eyesight is necessary. … For me, the inspiration is just to see if I run into any difficulties."
