Really?
1) Muggers
The LEO's I deal with are normally "Just give them your wallet and phone. Do not fight back."
Now, admittedly, most of this advice is from the US and being near big cities. In the US, we don't tend to have kidnappings--normally muggers will take your wallet and phone and run unless you are stupidly in some dangerous area.
2) Gangbangers
Generally will leave you alone unless it is a target of opportunity. However, teenagers are stupid and can consider truly bizarre things "disrespect". Combine this with drugs and you can get some exceptions.
3) Crazy/homeless
Generally the stuff they do never rises to the level of "I can shoot him" until it's too late for you to react.
And, this is, in fact, the crux of the situation. By the time the situation escalates to the level of "I am legally allowed to shoot this person" the situation is often too far gone for the gun to be helpful.
Now, I'm not a tiny female, so I don't present a "target of opportunity". However, women are more often the victim of the gun in the house from their partner than from random strangers.
Finally, my only interactions with concealed carry in my family are accidents where someone almost got shot unintentionally. Nobody in my extended family has ever had to use a gun to defend themselves, but there have been a handful of mishaps (thankfully, nobody harmed).
The statistics are against concealed carry except in fairly exceptional circumstances (jewelers, for example).
