Could be about time we started to lock up these idiots that bring prohibited items on board aircraft, 6-12 months should start to send the message that this is just not on.
The whole incident does sound a little odd to me, if a "normal" passenger was found to have a taser on them, you would expect that the whole terminal would be shut down and all the passengers re-screened (like what happened in Sydney). I guess the AFP knew better in this case.
