Ah yes.
You know the more I think about this whole Corby case, the more I start to understand why they gave her 20 years. I bet what's happened is she's gone to pick up her luggage, maybe realised there's something in there that wasn't supposed to be - like 4 kgs of pot in a boogie board which is probably going to make it noticeably heftier - she's gone to customs and shat herself when they ask her to open it up (apparently she refused at first) and whoopsy, hello, there's the wacky tabacky.
And the defence could have been better, they seemed to have relied mostly on circumstantial evidence and the whole 'it doesn't make sense' line...it doesn't make sense she would smuggle drugs, because she was coming to visit relatives, the street value is way higher in Australia, she's not the type, she doesn't have a record, she admitted the bag was hers and so on, which is not evidence at all. What they should have had was fingerprints taken from the bag, security tapes from airports at all stopovers, and the weight records of all her luggage. Without that she was totally screwed. There's no way the judges could have found her innocent with what was presented to them, they probably realise there is enough reasonable doubt which is why they didn't give her the death penalty or life imprisonment, but I bet with the case the defence made she would have got a similar and pretty harsh sentence if it was in an Australian court too.
