ACLU releases app for recording police action

The ACLU has released "Police Tape," an Android app that allows users to "securely and discreetly record and store interactions with police, as well as provide legal information about citizens' rights when interacting with the police." Videos are automatically uploaded to an external server, preventing deletion by law enforcement, and the app itself can run in the background while recording so it isn't obvious what is happening.

Recently, some states have enacted laws banning the recording of police action, though such a ban may be a violation of the First Amendment (read more here).
