It is a scary situation, and another good reason to be allowed to carry. But I got to thinking, suppose the person who sent the threat actually decided to do it. I don't know how much good having a firearm will do in that situation unless you encounter the person setting up the bomb. Even then would happen if you fired and the bullet impacted the bomb. Would it set it off? Don't get me wrong, I do believe that allowing people to have a way to defend themselves is a good idea, I just don't know if you would be able to prevent a tragedy such as a bomb explosion.
