There are numerous things keeping the Catholic Church from being penalized for the FLB practice. One is the money they surely spread around, another is that stupid, "we are our own nation" bullshit and yet another is the fact that it isn't typically happening in Vatican City. That last bit means that it is extraordinarily difficult to justify (in a legal sense), punishing the institution as a whole. You can only hope that the men doing it will be punished by the laws in the country where they committed the acts, which vary greatly as well. Let's say a bunch of Swedish people began robbing banks in different countries. Would it make sense (legally) to punish Sweden? No, you would have to punish each criminal individually according to the laws in the country where they broke the law. Now, I realize it is an imperfect analogy. Firstly, the Vatican has no right, in my mind, to be their own nation. Secondly, Swedish is a nationality, not a religion. Nonetheless, that analogy fits as far as the legalities of the issue go.
This practice of only punishing sparingly and only according to the law where the law was broken is flawed, to be sure. The whole thing is out of control and could be handled better, without trying to take down the Catholic Church. For example, a Catholic priest in California, who is from Ireland can rape babies and be punished by being sent back to Ireland to live as a free man. This has actually happened. Now, if that man were put in jail as long as an American would have been, his buddies would think "Oh shit, I'm not going to get away with fucking their kids." Since they are rarely punished, they look at it as a free for all. It's disgusting, but there you have it. I doubt the Catholic Church as a whole will ever be punished for these rapes and cover ups.
