Meanwhile, this:
> “If Google is allowed or required to turn over information in this Colorado case, there is nothing to stop a court in a state that has outlawed abortion to also require Google to turn over information on that kind of keyword search.”
seems like it's of entirely different magnitude, far less amenable to such a narrow scope.
That's all from a legal perspective. From a policy perspective, I think our search histories should not be collected in the first place as much as practically possible. In meatspace, libraries are actually very protective of what books you look up/checkout. Seattle City Library actually requires you to opt-in for tracking of your checkout history because they know this sort of data is sensitive.
