I think this is a bloody brilliant idea. Especially since parliament is in the process of dealing with the legislation to set up an Independent Police Complaints Authority. That legislation got put on hold while the rape inquiry is going on. So now is the perfect opportunity to amend that legislation to set up an IPI as well. This will probably help save costs of prisoners going to court every time they get their human rights trampled on at the very least. Hey, it might even get the 'bad' prison guards to treat them with a bit of respect.
I look forward to seeing how this one progresses.
