I dont think theres need to keep the "sheep" out of this. This just goes to show you/them that they can encounter many people everyday that may be carrying. This may be good friend, family, co-workers, etc. And if you think about it that way, you begin to see how not only criminals use/carry guns, that responsible, trustworthy people carry everyday, and follow the laws around carrying. Maybe if you can get the anti's to see this, you might have a chance at introducing them to guns in a safe and intelligent matter.
On a side note, his "practical/everyday" carry seems a little excessive to me...
