Yes, of course FAMs should always be in first class, because terrorists such as, for example, Richard Reid, are always in F. Oh, wait.........
Oh, I know: the Middle Easterners on that flight who were suspected of conspiring to build a bomb inside the lavatory. They were all in FC too, right? Oh, wait.....
Well, at least it's a good thing the FAMs are always in F (where everyone knows they usually are, thereby giving anyone who wants to evade or attack them a tactical advantage), because there is certainly nothing harmful that any terrorist could do in coach.
I mean, it's not like we even have reinforced cockpit doors to protect the pilots if a FAM isn't in F. Oh, wait....
