I feel very uncomfortable discussing Skymarshall operations on an open forum.
Perhaps those of you who are questioning the actions of this particular individual should think about the following.
1. No Skymarshall wants to reveal his presence or identity until absolutely necessary.
2. Terrorist hijackers don't usually operate alone...although they may pretend to be.
Those of you with half a brain and keeping in mind some of your basic security training should know what I'm saying.
Let's just drop it now folks.
