Looks like they're still trying to figure out if he was licensed. (I don't understand how this question couldn't be answered in a matter of seconds by authorities) But at any rate let us hope he was not to damper to arguments licensed carriers.
From what Chris Mortensen said, he was wearing it tucked in his waistband (cause, a holster woulda clashed with his outfit) and his friend/teammate noticed it was taking a dive, and he tried to grab it and *bang*
oops.
I've heard that an Unlicensed Gun in a bar will getcha 3 1/2 years, minimum.
