The fact is that the incarceration should have been secure. It was not. Therefore, the incarcerated has every right to sue, as the security of a judicial structure is also a judicial matter. It's an officers duty to prevent prison fights and keep members separated if need be. In many prisons, there are numerous gangs and underworld affiliates who rival each other. They have conflict not only in the streets, but in the halls too.
Many of the prisoners don't even belong to gangs. Some don't have any ties at all. Some may even be innocent (should innocents be the victim of random prisoner violence?). However, their reasons for being imprisoned are irrelevant from the issue.
No one's defending pedophilia (remember, pedophilia and pedophiles are two separate entities, just like sodomy and homosexuality are two separate entities). I'm pretty sure everyone in this thread thinks that man should be imprisoned if he broke the law. But two unlawful acts don't make a lawful act.
I'm still confused about how telling someone to ignore the Pope is supposedly sacrilegious.
Also, please be explicit about whether you agree or disagree instead of asking me if I agree about my own sardonic representation of the kind of reasoning you are using. I don't know if the Irish treat their inmates the same way the U.S. does.
Just because the legal system is often exploited doesn't mean that random people within it can impose their own moral agendas on it. That's not their responsibility.
