that would be an excellent place to start/.
One article that I found published On The Net on the 12th....quoted FBI guys as saying there was no Link TO Terrorism..which ordinarily means that the act so described was an act of terrorism...
I didnt find that article until this afternoon...
the claim was as far as I can determine not repeated in any other articles since. and I have looked for that denial...believe me.
this is one screwy scenario isnt it
and even the engineer was left to live...
if I was a terrorist, I guess I would make a better plan than try to sit in one spot silently and wait, wait, wait til just the exact moment I could get a shot off to hit the engineer....nearly impossible IMO from pics I have seen of the interior....
