The way I read it, he displayed a fake badge that indicated he had a CC permit. There is nothing that says he had a legitimate CCW permit.
Another article quoted the DA as saying the shooter showed his concealed carry permit, so if he didn't have one they would have charged him for carrying a deadly weapon without a permit I would think. He was charged with manslaughter and reckless endangerment.
Sounds like he had it in some kind of badge holder like you may use at work, something on a lanyard maybe. Definitely a few bricks short of a full load. Another article said he had flashed his permit before during another altercation and the other guy walked away.
