Another one?!?! what's next, will TSA need to start mental evaluations of all passengers?
Yes, exactly the knee-jerk reaction the 'free world' needs. There are millions of people all over the world with a variety of mental health problems, and unfortunately, these are on occasion unpredictable. Crew are more than capable of handling the majority of these, however scary it might initially appear.
You can't 100% control who gets on an aircraft, and how they'll behave. By far the biggest factor in onboard violence/disturbance is alcohol anyway.
