It was tongue-in-cheek when I said the ARM reset set him off. Just my morning humor. The article did imply that being underwater in his mortgage could have been one factor.
I agree with Voz that Enorah meant being a marine may have exposed him to some f’d up stuff. Although the comments about the “poor guy” make me feel that perhaps Enorah is with the ACLU or worked on OJ’s defense team.
Like marion said the dude was just plain nuts. There are plenty of military men (not just marines) who see f’d up stuff but don’t go crazy and harm civilians back home. There are also plenty of people with ARMs getting reset and they don’t go nuts.
