Wasn't arrested and won't be prosecuted. http://www.tmz.com/2015/09/02/dwight-howard-brings-loaded-gun-to-airport-doesnt-get-arrested/
Shhh. Just close your eyes. It'll all be over soon. Dwight is just trying to prove to the NBA he's not soft. First the snakes and now the loaded gun.
My very uneducated guess is no because there's probably not any official public record of this. It's basically just a rumor.
Harden: Strip clubs, NBA groupies and now Kardashians. Lawson: DUIs for days! Howard: Snakes and a Loaded Gun in the Airport. Rockets really want to be the villians of the NBA... :grin:
