A rather ‘interesting’ idea to make all airline passengers wear their own personal taser. First they use it to control the terrorists, then maybe drunk people and finally that bloke is row F that looked at you a bit funny. Could be handy technology however:
“Oh my god, his heart’s stopped beating!!”
“Don’t worry, I’ll save him. CLEAR!”
*woman three rows back convulses and falls over*
“Oops, sorry madam, pressed the wrong button”.
And what happens if you just slip a bit of rubber underneath it?
