It's clear now that there is no evidence that the shooter, Afghan national Rahmanullah Lakanwal, who was a killer trained by the CIA, was radicalized into islamic jihad.

Disgraced ex-CNN anchor (not journalist) Don Lemon accompanied leftist extremists into a christian church on private property to protest ICE. Journalism isn't journalism in the US if you break the law to do it. Not only did Lemon trespass he likely violated other laws and the US Constitution to do it. Your literal individual rights end where an other's begins. Conceal carry on private property case reviewed by SCOTUS.
