Florida makes it very easy to own and conceal a handgun. I guess that leads to both politeness, and caution.
If you want to structure society around fear, that is (I guess) a country's prerogative, but it's not something I (as a non-American) would ever support.
Which doesn’t stop NYC having many, many guns being concealed carry. Because of you are looking to commit violent crimes, what’s another felony vs. having the power of life and death over victims?
And if you are a likely target of violent crimes, what’s a concealed carry felony vs. being dead or having a family member assaulted or murdered because you couldn’t stop it?
