I have another reason why Corporations are asking "No OC" in their stores.
If Klingons carrying edged weapons were common, would they tolerate that? No. Why? Because regardless of the rights of the individual to carry whatever they please, there is also a commensurate responsibility to handle them without injuring other citizens in near proximity.
If you have been thru Basic Training, and carried a long arm 24/7 for weeks on end, you know - a front sight between the eyes, getting banged in the head, having the gun catch on the surroundings and impacting the carrier or another individual nearby, it all happens and it's entirely due to complete clumsiness and a lack of experience.
Hopefully no one with a tactical serrated muzzle device has a kid run up close and open up their scalp chasing their sister in the store. Klingon or OCT, it's going to be a ugly situation with the bloody child crying, an outraged mother in someone's face, security, EMT's, LEO's, management, lawyers, judges, and about 20 million people remembering the name of "that guy who OC'd and tore up the poor kid."
It won't be any less if it was a set of protected sight ears or whatever. Kids bounce around in stores, adults brush by, and if anything, the public being used to it means even more indifference and ignorance about the likelihood of ND's ricochets, etc.
There are very specific and strongly enforced rules in the military about when you do and don't carry loaded, all based not on the combat situation as much as what humans will do in error, and getting your team mates shot by negligent handling. It's exactly the reason why even CCW aren't welcome in some places. How many toilets have to be shot to make that point?
Apparently some still don't get it. OC as an expression of our specific legal rights isn't what is being opposed as much as the stupid things that happen when we do. I suspect that even an OC proponent who is center punched between the eyes by his buddy's rifle slipping off their shoulder will immediately compare their cranium to their colon and describe the similarity of it's contents.
If you have served, you've likely heard it, too. Explicitly. From your team mates, companions, Drill instructors, and commanders.
You don't just start OC'ing in public in a crowd of people without consequences. And that is exactly why the reasonable person does not. He knows it can happen, doesn't want it to happen to him, and by extension, does not do it out of consideration of others.
Only the truly arrogant and egotistical think it can't happen. And, when it does, the reality comes as a flash of light and a resounding sense of pain directly in their skull. For those who still don't get it, the application of the blunt end of the rifle to the same area reinforces the message, too.
Stupid people have a hard life. We all get stupid, the smarter ones extend the lessons to other parts of their life. ie, Klingons with edged weapons are not welcome in the store.
Not rocket science to see why customers are being asked not to carry, and why employees are restricted completely. I might chafe against my rights being denied, but reality is that I really don't want to OC all day long when I'm busy waiting on customers. And those customers that do OC aren't getting by that easy when they add what they have purchased to what they are already carrying.
Slung rifle, check. Curtain rods, check, four foot flourescent tubes, check, broom, check, axe, check, 8 foot PVC, check, trim boards, check.
You gotta be kidding me. Put it in a cart? Sure, the rifle goes first at the front door, I'll push it down the aisles, thank you.
