Why did he have a gun in a nightclub? Kind of breaking the law?
No one should ever take a gun in a bar. You are asking for lawsuits or jail time.
I will not even drive my ATV with a loaded when I hunt groundhogs. One wrong bump in a furrow and a trigger hit and bang.
Always assume the gun will go off unexpectedly and never point it at yourself or anyone else at anytime. Always know the backstop.
My two cents.
Go lance! The underdog rises!
