I'm all for that, and I can think of a few other steps.
BTW, one poster stated on another thread that the shooter had more than one ID... I'm trying to track down a link.
There is nothing more perilous to us right now than the legions of foreign nationals who move within and outside our borders under fraudulent, untrackable and multiple identities. Abdul Ramadan comes into our country on a temp visa, he becomes Rasheed Mohammed and Sayed Al-Amman while he's here, he leaves the country as Abdul Ramadan as mandated, and he comes back as Rasheed or Sayed through American visas or through Toronto or Vancouver or the Virgin Islands. Nobody in our government, law enforcement agencies or immigration institutions knows who these guys REALLY ARE. Let's you and I try to go to Bulgaria, Norway or Argentina and pull that shit.
