Yea, as sad as it is they are just trying to get ahead of the ball here because the writing is on the wall that once again a 3rd party service provider is required to act as an agency of law enforcement.
Law enforcement should be saying "sure please leave those up so we can track down the actual criminals instead of sending them to another 1000 little 'dark webs'. But alas, the easiest and most public thing is to tell google how serious they are about the problem and require them to do something about it.
Google should not have to filter any website, ever. Regardless of the content if it meets the same selection and searching algorithms every other site does. That they are or do is playing censor at the governments behest and when they are doing that they have no longer any reason to be trusted no matter what you are searching for.
