Personally, I think we should adopt the same penalty as Bali for drug smugglers, that would send an even stronger signal . As it is they are deported back to their own country where they can continue and try to devise new methoads of bringing the bastard stuff in.
Either that or make them take their own medicine. All of it. Same applies to the old bitch in court yesterday. Give her a mega dose for aiding and abetting the misery of others.
