Correct me if I am wrong, but there is no indication of the door being armed and disarmed from the outside of the aircraft correct?

Only reason why I asked is because I was on an MD80 from LGA-MCO a few months back and I was in 1C and positioned to be first off. I watched as the F/A failed to disarm the slide (however its done on the MD80) and start to freak out and told the agent to stop opening the door.

Personally, I think this policy is back assward and that only the F/As should open the door because I would have been in a world of hurt had the F/A not noticed she forgot to disarm the slide.
