It would be foolhardy for air marshals to identify themselves unless they are ready to make arrests. Recently, a Russian woman struck a male flight attendant before takeoff because she wouldn't turn off her cellphone on the tarmac. What resulted was all three air marshals getting up from their seats to arrest her.
Fine, except it makes for a great diversion to identify where the air marshals are sitting.
Of course nothing else happened on that flight, but we have to think out of the box if they're thinking out of the box.
That's just the attitude that will kill us.
Air Marshals are not law enforcement they are (or should be) warriors.
All these clowns should have been handcuffed and immobilized.
If the other passengers are terrified to the point of tears and the marshals are waiting for "something" to "happen" so they can "make an arrest" then we still don't understand we are at war.
The marshals inaction is scarier than the ME characters behavior.
