I find it hard to understand why people seem to think Ablett should've known what was going on? I've got mates who've smoked and grown 6 foot pot plants in their backyards for years and they've kept it a secret from their wives, kids and other family and friends who were against it. How hard would it be to hide it from fellow workmates who they don't even live with? One of my mates had a 10ft tree growing in his front yard (no fence) on Mount Tambourine.
