I lived for several decades in a certain crime-ridden Third World country, whose capital city is regarded as one if the more dangerous places in the world. Furthermore, some of its outlying districts - such as the one I lived in - are even worse. In common with most expatriates who have experienced that country, I could go on all day with stories which fit the category of “The truth is stranger than fiction.”
From that experience, I have serious reservations about the level of protection afforded by carrying a firearm on ones person.
The only persons whom I knew who got shot were both carrying a 9mm automatic (which both of them knew well how to use).
Maybe the Australian country singer John Williamson got it right in one of his songs - a stanza of which reads “ The way to get shot is to carry a gun”.
