The amazing amount of uninformed speculation that's coming out of the mouth of Chris Matthews right now is mind numbing. Speaking as someone who lives and works on a military post, I have absolutely no doubt that I have a better understanding of the dynamics of the military base than he does.
I'm just going to hit some of the major issues.
1: In the United States Army, it's hard to describe a Major as a "high ranking officer". It's typically a mid-career rank. Given that there are somewhere around 5000 officers assigned at Fort Hood, I would be surprised if there were fewer than 500 Majors assigned to the post. I would not be surprised if there were 1000.
2: As one of the guests has repeatedly pointed out to Matthews, it is not yet certain that there was more than one gunman involved. It's possible that the two additional people arrested were involved. It's also possible that the MPs were erring on the side of caution, and grabbed everyone who might have been involved. Any speculation about motives is just that - speculation.
3: Given that Gov. Perry didn't have the updated number of injured when he made his statement, I'd give the 3-star's statement that the arrested suspects are not confirmed shooters more credence than Perry's statement that all 3 were shooters.
4: Regarding the "lax security" question that someone asked in Perry's press conference: there's only so tight you can lock down an active-duty post and still keep things functioning.
5: Rep Sestak is discussing this as a mental health issue, and an issue regarding mental health care available to the military. Whether that's relevant to today's tragedy or not - and it's looking increasingly likely that it is - he's right.
6: Regarding the recent promotion of the identified shooter: the criteria for promotion to major in the medical corps are not very rigid at all. If you don't massively screw up, you get promoted.
7: The more details I here about Hasan, the more bizzare this sounds. He's apparently a psychiatrist who graduated from Uniformed Services University Med School. That's about the least likely person I can think of to be involved in this.
8: Matthews is even less informed this hour than he was at 4. That must have taken some effort.
9: The lack of information about casualties is not a surprise. It's likely that at least some of them do not have local next of kin, and notifications may take some time.
10: Yeah, Chris Matthews is a flaming idiot. Army Officers, even psychiatrists, are expected to know how to shoot a handgun.
11: Pete Williams has some knowledge deficits, too. Hasan would have been treating patients throughout his residency. And it's entirely possible that he only found out about the deployment very recently. It's not at all unusual for doctors to get last minute orders. Doctors are frequently last-minute plugins for deploying units.
12: No, he got the MD first, then the MPH.
13: I'm somewhat surprised that Olbermann is going with his regular program. But at least it will cut down on the massively uninformed speculation about Ft. Hood.
