Over the weekend, someone called in a bomb threat for one of the businesses in Nashville's Lower Broadway tourist district. My first thought was there could be a connection to 9/11. I don't know how the two might connect, but that's often my first thought when tragedy strikes this time of year. I've never understood the purpose of bomb threats. Do people call them in to cause panic? Many people suffer from mental health issues, but I don't understand the point. I must be missing something...
