Why Mass Shootings Happen and How to Stop Them

I had plans to record an introductory philosophical episode today but unfortunately woke up to the horrible news of mass shooting of kids at the Robb Elementary School by a teenage gunman. So I decided to do an episode on what is the root cause behind all this. Is it gun control only or there are hidden issues that needs to be addressed to stop the mass shootings. My heart goes out to the students and their family of Robb Elementary School, Texas.
