WASHINGTON (AP) -- The Virginia Tech shootings have left more women than men troubled by gun violence and favoring tighter firearms laws, though overall most Americans express little concern they might become a gun crime victim, a new AP-Ipsos poll has found. Minorities and city residents also showed greater worry about gun crimes and a higher preference for stricter gun controls, according to the survey, taken after Monday's mayhem in which 32 students and teachers plus the gunman died.
