I don't know how it is in other states but in CO if you are in fear of your life you can defend yourself with a concealed weapon and be immune of any civil lawsuit (as long as you are in the right to use force to defend yourself), says it right there in the law itself.
Allow me to explore a scenario with you. It may be unlikely, but it could've happened. Imagine this kid and his 2 methed out friends disabled your car by ramming it. You said you got out after he did so, but then he just drove off. Just as likely, they all could've gotten out and came at you (this sounds like what they wanted to happen before ramming you). Now imagine this road you were on, I don't know if it was rural or not, but imagine that there wasn't any traffic passing by for some reason. Just a break in traffic or not a heavily traveled road. You are by yourself with a disabled car and you are outnumbered three to one. These fools are methed out which means if they got ahold of you they'd probably kill you. If you decide to run (which is what I'm hoping any of us would do, unless you are a certified bad-ass), they would most likely do one of two things; 1) chase you 2) fuck your car up and leave. Either way you lose.
Now imagine that you have a concealed weapon and you have a permit to carry. They get out of the truck and come toward you, you pull your gun out of your jacket/car and show it two them. Now in this scenario also they have two choices; 1) they could continue to come after you (in which point you would need to determine by their body language, facial expressions, etc. how to react with your weapon. This is the grey area, I hope it would never come to this but you never know when drugs are involved. Me, I'd give a verbal warning to stop where they are and get back in the truck, if disobeyed, then I'd start shooting.) or 2) Probably the more likely of the two choices, they would just see the weapon and get back in the truck and leave.
The most likely outcome of the situation is them getting back in the truck and leaving after you pull your weapon because you are in control of the situation. BY HAVING THE GUN, YOU HAVE AVERTED VIOLENCE. I'm not saying you have to start shooting by having a concealed weapon, but a handgun sure does put a huge exclamation point on, "Back the F*CK UP!!"
People in this country forget that the right to bear arms is a constitutional right. Its the god damn second amendment; right behind free speech for christ sakes!! And hardly anyone in this country uses it!! Am I saying everyone go out, buy a gun, and start shooting people when they piss you off??? No, of course not. But to have one in a situation similar to the one above, it could save your life.
Bring on the rebuttals!!!!!!!!!!
