I don't know why I would have expected anything about the entire incident to make sense, but the more I hear about the alleged shooter - Malik Nidal Hasan - the less sense it seems to make. I'm not going to try to speculate about anything at this point. Here are the things that are known so far:
1: He was born in VA.
2: He received his medical degree at Uniformed Services University of Health Sciences in 2003.
3: He immediately followed this up with a psychiatry residency at Walter Reed, which he completed in 2007.
4: He did a fellowship in Disaster and Preventative Psychiatry back at USUHS, which he recently finished.
5: He recently pinned on Major, which would put his promotion in the same time frame as the rest of the year group.
