1. I think he is a completely out-of-mind person. Probably he was unhappy and unsatisfied about his life. He probably needed friends or people around him that he didn't have. It scares me because if a person can do that in a military place someone could do it easily in a mall or in a hospital.
2. I think he is a terrorist, for his strange beliefs, but I don't think there was an organization behind him.
3. Probably he was always discriminated for his religion and his race in his career. This discrimination probably brought him to believe what he believes, and to do what he did.
4. I don't think a lot of Muslims have his same feelings. He probably was affected by deseases and he had very strange and extreme feelings and beliefs.
5. I think the only fault we can give to the military is to have discriminated him. He probably felt like his fait was discriminated, that's why his beliefs were so strong and angry. Anyway there were no signs he was going to do that. Maybe military psychiatrists should be monitored by someone if it is really so stressful as Ragan says.
6. Someone had do it. She was the brave one who did it.
