I'm going to have to agree with Street Pilot and Beavis.
I am personally for concealed carry. I'm debating over getting it, but I probably would not carry. I would mainly get it to become a statistic of being pro-carry.
Take a hard look into Ohio laws before you ever decide to carry. If you shoot someone, there is very little chance that you can escape being convicted of something and thrown in jail, even if you do everything right. Last I heard, in Ohio you have the responsibility to flee, unlike states like Texas or Florida, which is where you hear about all the people that put their CCW to good use. What this means to you, is that you have the responsibility to remove yourself from the situation if at all possible, whether there is someone in your house or someone pointing a gun at you on the street. If you decide to pull a weapon, it's now your job to prove that you had no way out, and it was your last resort. The laws that state this makes it almost senseless to carry, its just not worth the headache, unless you constantly find yourself in areas where you feel that you may be harmed.
Your friend did the smart thing in his situation. Him pulling a gun would have only made things far, far worse. If this were Texas and he shot all three of them, he would have gotten a medal.
