PAX Britannica --
A passenger has been injured (by a taser) on an aircraft.
Thank you for some sense. The passenger could have been killed - not unknown with TASERs. As for his behaviour it could have been a (physical) illness, dehydration, unbalanced electrolytes, prescription medicine with interrupted meals, fluids, sleep etc. This was someone's brother, father, or son. Even if he was mentally ill or a 'bad person' does he deserve that degree of potentially lethal force in that environment?
I think it stinks that folk believe their convenience outweighs the life and safety of a passenger.
