The Fort Lauderdale shooter, Esteban Santiago, was one of us too — a New Jersey-born Iraq veteran. Santiago, like many other mishandled veterans, came back damaged from war. He heard voices, he was unstable. He joined the Alaska National Guard and the Army Reserves after returning home, but received a less-than-honorable discharge. He was arrested for domestic violence. Two months ago he walked into an FBI office and said voices told him to join ISIS. He spit out a barrage of crazy conspiracy theories. No one took his gun(s) away.
