Are you just trying to start an argument for the sake of it?
They can do what they like when in prison. If they're locked up, they can't affect me, you or anyone else that isn't near them (such as prison staff or other prisoners).
I didn't think I needed to add a disclaimer to my post, which was quite obvious and I even tried to clarify. I think you're being overly pedantic now.
If the person that stabbed the inspector is let out sooner rather than later and does commit more offences, could it affect you or me then perhaps? All I said is that when they're locked up, they're definitely not a problem to us.
