armed security is always a roadblock. only the truly insane spend their one life in taking 21. it's not a "gun problem" it's a sanity problem. Many insane people believe they are larger than life. that they are immortal. I'm guessing here ; I have never had the desire to take anyone's life. sane people know that it's not going to hurt the people they kill, they are dead and feel nothing, it's the people they leave behind that suffer for the rest of their lives.
