Let me tell ya'll about open carry and the % of those who actually use their firearms for their intended purpose. Apart from the fact that 10% of cops are killed by assailants stealing their weapon and turning in on them, why would you want to even advertise the fact you're armed?
To me, if I was a criminal, the fact you're carrying a open weapon tells me a lot about you and makes committing a crime against you that much easier. And then, if you are an open-carry, if confronted, you have to be 'programmed' to shoot to kill, and shoot accurately with a really crappy weapon for accuracy and not accidently hit a loved one or innocent because you'll be charged with manslaughter. And so on it goes. And if a crook has half a brain, you're showing them what you got and how truly vulnerable you are.
If you insist on carrying a weapon, get a concealed permit. And then get to the range to get good at shooting effectively and accurately without thinking. Because if you cannot shoot well without thinking, you may be better and safer by keep your guns for the range because you're a liability to others and your family/self.
Vaccinations don't work when only 1%, 10%, or even 20% are vaccinated - a large majority has to partake for it to be effective. The right to bear arms was intended to work similarly. The majority was supposed to be armed, so that it didn't matter if you could see if someone was armed or not, as anyone and everyone else around you likely was. In today's society, carrying weapons in any capacity is still a minority in most communities (regardless of how accepted it is).
Your argument fails to address this, and focuses on the open carry aspect instead of the fact that the open carrier is likely the only carrier in the area.
If you switch your example to a community where 65% of the community carries a weapon (either concealed or otherwise), it wouldn't matter who was carrying openly, even with a criminal present, because he has a 2 in 3 chance of running into someone else armed.
The issue with open carry is not open carry itself, it's the fact that carrying a weapon is rare enough as it is that it makes you a target of opportunity, just like driving a Lamborghini in downtown Detroit would make you a prime target not because of the Lamborghini, but rather the fact they aren't common given the populace. The police in England used to have (and still do, to some degree) the exact same issue of having their weapons stolen.
