SEATTLE (AP) - As the U.S. looks for ways to respond to mass shootings at schools, some say more people should carry guns, including teachers.

An Associated Press investigation documented 1,422 unintentional shootings by officers at 258 agencies since 2012. Twenty-two occurred at schools. Experts note that law officers get more specialized firearms training than most but say it’s still insufficient.
