Which means they are federal employees.
A civilian is the guy working on the 70th floor of the World Trade Center. We can play the semantics game all night long if you want... but nobody of any authority has claimed that this is a terrorist attack... so civilians or not it doesn't mean this guy is a terrorist.
I'm sorry, but federal employees are civilians. The military are not civilians.
And this most certainly was a terrorist attack...despite the fact that it was not Muslims doing it.
I think that you and people like you are just pissed because now you can't go around and say that all terrorist attacks have been by Muslims. (of course, that was never true in the first place...but whatever)
