You see no loss of an advantage of someone not knowing you are armed?"SMART THING" is a relative comment - it's relative to their opinion of what 'smart' is. I don't see any tactical advantage to losing the element of surprise...IMHO, decisions have consequences (regardless of your personal reasons for making them)...nobody is forcing them, they can still open carry, they just have to be prepared to live with the consequences...
ok how about this.. Guy cases a McDonalds to kill everyone. he's 4 people in line behind a guy packing openly. Who is his first target? The armed man giving his order and distracted or the 5 year old eating a happy meal?
It's relatively smart not to play hacky sack in the middle Atlanta traffic on I75 at lunch time.
