This one is refreshingly clear and simple – at least if one applies reason. A guy declares he has a bomb, and refuses orders of a Sky Marshal, and then reaches into his bag – it’s a no-brainer call!
In this world of suicide bombers around the world, it’s definitely time to apply some 9 mm behavioral control. As far as the wife trying to say that he was bipolar and off his meds – maybe so, but with a plane full of people the Marshall had no option to stop and run an investigation.
Claiming a bomb and reaching into a bag is tantamount to drawing a gun and pointing it at the officer. Bang! Problem resolved, everyone except the perp safe.
The Sky Marshal did his job. That’s what he was there for.
