An anonymous reader writes "Vigilant Solutions maintains what they claim is the nation's largest database of license-plate tracking data, 'LEARN' (Law Enforcement Archival and Reporting Network). But when a law enforcement agency signs up to use the database, they are sworn to keep it secret. The reason? They are quite clear about that: 'to prohibit users from cooperating with any media outlet to bring attention to LEARN or LEARN-NVLS.' So, they're tracking you (they're tracking everybody)... but they don't want you to know. The agreement, uncovered by the Electronic Frontier Foundation, states: You shall not create, publish, distribute, or permit any written, electronically transmitted or other form of publicity material that makes reference to LEARN or this Agreement without first submitting the material to LEARN-NVLS and receiving written consent from LEARN-NVLS. This prohibition is specifically intended to prohibit users from cooperating with any media outlet to bring attention to LEARN or LEARN-NVLS. Breach this provision may result in LEARN-NVLS immediately termination of this Agreement upon notice to you."
Immediately after WIRED published the story, though, the agreement mysteriously changed. The secrecy provision is still there, but the statement that it's 'specifically intended' to prevent the media attention has vanished."
