LMD,
You're right, I would also be upset if someone wasn't doing their job properly. However I feel the job of skymarshal is unneccesary in the U.S. if proper security procedures are used on the ground.
UK airlines have flown in and out of Belfast in Northern Ireland, which up until recently was a terrorist heartland, without the need for a skymarshal and without incident. The money and effort used to train skymarsals would be better spent on effective security on the ground, by the time some mad mullah gets on an aircraft it is too late.

P.S. 4lla, let me know of any grammar or speling mistakes.
