No, I'd rather cockpit and cabin crews show enough intelligence to know that neither the word "bob" being written on a barf bag nor the presence of a passenger drinking from a bottle of water, nor a Japanese businessman (non-native english speaker) being confused about the precise definition of "suicide bomber" in a news article about the middle east are grounds for diverting an aircraft.

Emergency procedures and first-responders' valuable time should be saved for actual emergencies.
