We could debate the relative effectiveness of different forms of penalty, and the relative importance of punishment/deterrent, ongoing protection, and rehabilitation, but I'm not sure this is the forum for it.
However, let me be clear: if the facts in this case really are as I've seen reported, then I have no problem with taking people who did this, throwing them in a cage, and depriving society of their "productivity" for a while. As far as I'm concerned, that kind of productivity is about as welcome as the banking executives who command "competitive compensation packages" for running their organisations into the ground or the politicians who once elected proceed to legislate for the highest bidder.
