Not all search warrants are bad. Indeed, most of them are perfectly legitimate, and meet the qualifications under the 4th Amendment that there is probable cause of a crime being committed, and the warrant is narrowly tailored to seek out evidence to support that. But... not always. As Ken "Popehat" White explains in a recent blog post, the Justice Department has somehow obtained the mother-of-all bad search warrants while trying to track down people who were involved in protests of Donald Trump's inauguration back in January. The government has brought felony charges against a bunch of protestors from the inauguration, and now it appears the DOJ is going on a big fishing expedition.

As Ken notes, it's quite likely that some protestors committed crimes, for which they can be charged, but prosecutors in the case have decided to go ridiculously overbroad in trying to get any info they can find on protestors. They got a search warrant for the well known hosting company DreamHost, who hosts the site disruptj20.org (as an aside, the fact that a site like that doesn't default to HTTPS for all connections is really, really unfortunate, especially given the rest of this article). The warrant basically demands everything that DreamHost could possibly have on anyone who did anything on disruptj20, including just visiting. As White notes in his post, it's not that unreasonable that the DOJ sought to find out who ran the site, but now they're requesting basically everything, which likely includes the IP addresses of all visitors:
