Regarding #2, I always thought that a LEO needed probable cause that a crime was being committed in order to stop anyone (general statement not limited to just carrying a gun). And I further thought that just having a handgun was not probable cause (by itself), any more than seeing someone driving a car would be probable cause that they are an unlicensed driver.

Of course now, seeing someone with a gun would be even less probable cause of a crime since people can legally carry without a license.
