How does having the data tell the EFF how they are using the data? If you give me a spreadsheet with a bunch of data in it, I don't know how you use it.
Are they using it legally? How can we know just by looking at the data they have?

On police cruisers, which indiscriminately scan as they drive through any neighborhood.
Do they change the data or delete "special" cars or "special" events. If there are any exceptions to collecting and storing the data, we can't trust it for much of anything: maybe the license plate entry was changed to a different license, maybe seeing a license at a location was added to the data, maybe other suspects are ruled out because data was deleted. And there will absolutly be exceptions: undercover officers, the presidents motorcade, people with stalkers, etc...
Cross references won't be easy.
