You bring up some fair points. And you are right, she shouldn't be convicted because of her family history. However, there are so many damning facts which don't support her.
However, if your theory on a baggage handler "accidently" letting the boogie board go through, it would have to be one of the biggest coincidences of all time.
The 'accidental' baggage theory just happened to attach itself to a girl who has a sordid history in drugs, a father who was found to grow and distribute, a brother with drug convictions. The same girl who "accidently" got packed the drugs by baggage handlers was actually photographed only months prior with one of the biggest drug distributors in Australia. The same girl who said, "I have never taken drugs, nor would i know what they looked like" was photographed with a bong months prior to getting caught. It would have to be the greatest/unluckiest coincidences of all time that she "accidently" received the package.
On top of this, her sister's best friend spilt the beans acknowledged Corby's guilt.
And Corby refused a DNA test of the baggage/pot. Bloody hell, if i were not guilty and had thought a handler did it, i would jump all over a DNA test of the pot.
Her sister's best friend spilt the beans on the whole affair telling the media exactly what happened.
We all hear the theories pro and con as you say. I have a few friends who a federal cops and they are strong in their belief and that the person in question was not new to them.
Too many stars align as far as I am concerned and it is much creditable than a package "accidently" being associated with a frequent traveller to Indo who has a sordid history and was photographed with a sordid character only months prior.
Oh, and this sordid character was one of the first to travel to Bali to visit her in prison. Unfortunately, the photo of her with him came out a few months later.
