Releasing that data publicly could be dangerous. Which kind of goes to show that the police shouldn't have that kind of data to begin with.

That's the point the EFF is trying to make, but it's also absurd. It would obviously be dangerous for them to release their donors' credit card details in public (or even store them in a non-encrypted database and non-PCI compliant manner), but that's an argument for limiting who has access to how much of the records and not an argument that credit cards and financial transactions data shouldn't exist.
