I certainly agree with that. But I don't think this was an Al Qaeda-directed attack. Looks like it was definitely Al Qaeda-inspired, in that Hasan viewed himself as participating in the great anti-Anerican jihad that Al Qaeda promotes. But as for his connections to Al Qaeda, I think he was a wannabe, and that they may even have been trying to rebuff him, because they could tell he was a loose cannon that couldn't be counted on to follow orders.
That could be so. Hopefully, the investigations will be successful and all necessary security measures taken. I’d feel more comfortable if those in charge gave me reason for more faith in them.
