Two from Wisconsin were killed and another wounded. He was a discipline problem, didn't get along with others, was a bit of a loner AND a psychiatrist (never met one who wasn't a big bag of issues) and this didn't raise any flags? It's not the first time that a Muslim in the US military turned on US troops but it's the worst incident of this kind at a US base. Even with his problems, he still made Major.
Sorry, but profiling would have kept this from happening.
