Because the Judge cannot go by what he reads on the internet, or sees on CNN. He can only go by what has been filed in court by the prosecutor, and the law. The women were charged with child abuse, not terrorism.
Judge McElroy was fully aware of all details relative to the terror camp, its horrors and the monsters who were running it.
He learned those details at first hand, not from CNN, TV or the internet.

Judge McElroy was criminally lax where he should have been judicially proactive in the service of the people he has sworn to protect.
