The only thing you can be charged with is Criminal Trespass assuming you are found carrying (improperly concealing your weapon) or you are forced to use deadly force to save yourself or another person. Then, the Casino must call the police and press charges against you. If you are properly carrying and are training to only use deadly force when you are in fear for your life or grave bodily harm, this situation will be a rare occurence. If it does occur and you were able to remove the threat to yourself and possibly save other innocent lives, the chances of the Casino pressing charges is remote. You may even get a free stack of chips. PS I do not recommend going anywhere and consuming alcohol as you move into the impaired judgement area which is not a place to be.
