Of course it is the point.
Of course its not the point. The point is calling 911, IF a situation ever does come about with someone waving a gun around, and you "getting into trouble". That IS what you said you'd do.
This might be some incredible revelation, but unless you're a gang member or in an active military zone, MOST folks never think they're going to run into someone with a gun. Myself included. It's just nice to know that IF that were to happen, I have more than waiting perhaps 10+minutes, to defend me and my loved ones
So, no, a simple concealed firearm, with the person having taken safety classes in their use, will do just fine.
