What a terrible, terrible law.
Speculation and accusation are enough to totally ostracise a person from society, emotionally cripple them, and to financially bankrupt them with legal defence costs.
Possession laws need to be repealed. They're too broad, and a waste of time and money. Bear in mind that this was 11 months of court fees, investigation by police and forensic experts, and all at the expense of the tax payer. These resources could be put towards finding the distributors and creators of these abhorrent materials, instead of ruining the lives of not just one person, but his family, his friends, and his colleagues; After all, they were all associated with a pervert, weren't they?
