It‘s no secret that various law enforcement and government agencies „monitor“ Twitter, and sometimes to do that properly, they need to have an actual Twitter account. Apparently for Homeland Security, that Twitter account is @DHSNOCMMC1, which (as you might imagine) is a „protected“ account, so you can‘t see its tweets. However, Carlton Purvis noticed that this account followed a few hundred other Twitter users, and wondered who they were. Purvis filed a FOIA request, asking for the follower list, but also for any authorized apps and widgets that DHS uses.
