You clearly proved that the easy access to guns is not responsible nor the mental illness. I also feel that people who can't express their thought and don't get heard by people try to do it. I don't want to specify any specific race or religion "Gamma Males " or "Muslim " or Any other religion. I just want to say that we should focus on moral education, focus on family relationship and things that help people to understand each other.

In Bangladesh, We do have terrorist attack several times, but we don't have access to guns easily. People who kill innocents human has no race or religion. Their religion is terrorist, their race is terrorism. So many valuable comment here I found. Thanks for your good post.
