In the whole of the Catholic Church in the US, this problem does not concern large numbers of priests, though it is very hurtful. The article is written to make it sound like Fr. Groeschel is blowing the problem off, when it seems to me he's only putting it into perspective. The above quote shows where the majority of the problems lie, and that can only be solved by weeding out those men during their Seminary training when it shows up, and it always does.
He may have sent a few priests back to active ministry, but remember, the most egregious of these molesters are usually described as nice men who are very popular in their Parishes. They could very well have snowed the therapists into thinking they were just fine and could be trusted again.
If you listen to Fr. Groeschel enough you'll notice that he's enamored of his degree in psychology. He mentions it quite a bit. For this he can be faulted, as he can be faulted for recommending the reassignment of molesting priests, if that's what he in fact did.
However, for working in the slums of NY for almost his entire adult life, he can't be faulted. A passage about splinters and planks comes to mind.
