My friend remarked to me that she felt (and heard her brother say) that we should enable our senior citizens to carry, and carry openly, because this is the segment of the population that is more educated, calmer, more circumspect, slower to anger, more mature and wiser (for the most part) and doing so would have an effect on society similar to 'an armed society is a polite society', IMO.
I'm talking about retired civil servants, retired professionals, lawyers, doctors, clinicians, and especially retired females. Let them open carry everywhere and across state lines. What's the problem? It wouldn't be one that separates states now (variations in 'training').
Heck, I think the state should buy all retired females who want to carry, pink handled revolvers, and free training if they want it. (no BG is gonna 'steal' a pink gun, after all, lol)
