Having a gun will NOT protect you

A teenage boy in America killed his mother, father and brother this week.  He shot them all with a rifle that his parents kept in their bedroom.  If asked why they had a rifle in their bedroom, I bet my bottom dollar that the answer would have been, "for protection".  Well, news flash, it didn't work.  I just cannot comprehend why people would think that owning a gun is protection.  If you go to the cinema and you have a gun in your bag and someone with an automatic rifle starts blinding shooting, how is having a gun going to protect you?  Are you going to ask him to wait while you find your bag and retrieve your gun?  No, didn't think so!
