Don't take what I'm saying the wrong way, I'm not saying he did it because he was a Muslim. I still hold to my position that he did this because he is a psychopathic a-hole. However, it does appear to be at the least politically (internally within the base) motivated shooting that was done to make a statement and instill fear into people.
I think that is a fair statement. I think the idea of terrorism has been used to talk more about a coordinated effort than your definition (also a valid one). Certainly I think this guy was nuts and was either inspired by, or used as justification, the political/religious reasons. Though I doubt very seriously this was any plan beyond this one guy.
I agree.
I do think he planned to do this and didn't just "snap" but I dont think he was directed by al-quaeda or some other terrorist network.
Does a terrorist attack have to be directed by some foreign entity? A terrorist is someone that is trying to make a statement. Did the shooter make any demands or leave any evidence of wrongs he was supposedly righting? Is going postal in itself a terrorist attack? I think it was more akin to a workplace shooting.
