The sunrise this morning brought with it news of another tragedy: this time, a senseless act of violence at a concert in Las Vegas. At last count, 50 people are dead and more than 200 are injured. All at the hands of a lone gunman who perched himself high above a crowd and allowed sadness and anger to rain down in bullets. Though this is the most deadly mass shooting in our country's history, it was not certainly not the first, nor will it be the last. Whenever something like this happens, regardless of scale, we are left with questions that have no easy answers.
