Too late to edit.
I wanted to add that I am planning a solo driving trip halfway across the country this year. I am a single woman, relatively young (not an old bat by any means, even if my niece likes to make jokes about it), fairly attractive, and not terribly muscular or intimidating looking (5'9" and 140lbs). Am I genuinely worried that I'm going to get raped, robbed, beaten, and murdered? No, if I was I'd be a fool to take the trip. However, there is always a chance that you will encounter a situation where someone decides you're a good target. It's an unfortunate reality that there are bad people out there. So I'm taking self defense classes, applied for and received my permit to carry, will be training with my gun not only in shooting, but also in retention and how to get it back if necessary. It's not about being paranoid, it's about being prepared to protect yourself if necessary. Since the government isn't going to pay someone to follow me around and make sure I'm safe, I figure I should probably be prepared to take care of myself. Hell not sure if I want someone following me around all the time, they'd probably think I was crazy with all the time I spend discussing topics like this.
ETA - AGAIN I will note that I'm not even worried about these people necessarily being armed. Either which way, they are probably bigger, stronger, more aggressive, and don't have many compunctions about hurting someone to get what they want. If they happen to be armed, well that's where all my practice comes in.
