Know Your Rights When You Are Stopped or Detained for Taking Photographs

The America Civil Liberties Union has created a free resource which outlines photographers' rights and tips on what to do if those rights are infringed upon.

From the ACLU:

Taking photographs of things that are plainly visible from public spaces is a constitutional right – and that includes federal buildings, transportation facilities, and police and other government officials carrying out their duties. Unfortunately, there is a widespread, continuing pattern of law enforcement officers ordering people to stop taking photographs from public places, and harassing, detaining and arresting those who fail to comply.
