We commend for her strongly worded letter condemning the mass police surveillance enabled by Fog Data Science. We hope that the will act quickly to stop the data broker industry that leads to these privacy invasions.

Of course, the DOJ advocates for maximum secrecy for search warrant materials during early stages. Which can frustrate public access into docs showing surveillance, because so many warrants don't lead to indictments.

I have no insight into DOJ, but the "pre-indictment" language isn't sly. It's describing the law around when the public's First Amendment right of access attaches to search warrant materials. It doesn't imply that an indictment is or is not coming.

There's a sly reference, by quotation of a recent case, that this search took place in "the pre-indictment stage" of the case. See footnote 2. twitter.com/kyledcheney/st…

Now would be a great time to submit your 2020 FOIA horror story so we can name and shame them during Sunshine Week.

Great FOIA win!!

After 10 months - we finally got the 9th Circuit's decision in a huge FOIA case, stating that 1) requesters can indeed get statistical gun data from ATF (which has not occurred in OVER a decade) and 2) querying government databases does not amount to creation of a new record. twitter.com/ShawnMusgrave/…
