I take the view there are 4 purposes behind prison, your three and setting a deterrent.
Edwards was not a passive recipient of these images, refer BK Brian’s post above, he was actively engaged in obtaining them.
Behind child pornography are layers of abuse, it is a crime with real victims who are vulnerable children.
Its a ‘business’ driven by demand, and Edwards has clearly been part of that demand driving the abuse.
I take particular objection to ‘he’s lost his reputation and his career’ being considered in sentencing or what is an appropriate punishment.
He had no right to that reputation or that career, he engaging in filth behind a cloak of decency, he was never decent.
Moreover, it’s an argument often used (in the UK) when considering the sentencing of criminals who have ‘successful lives’ an argument not available to those who are not privileged with wealth and social capital.
Now I think you and I might find a great deal of agreement on the failings of the penal system, there is a lot wrong with prisons and rehabilitation, but this isn’t about what is wrong with prison, it’s about a privileged, wealthy, connected man being treated very leniently by the courts.
He’s a pervert, he belongs behind bars.
