The Freedom of Information Act or FOIA is the liberty for citizens on the United States to access information about the United States Government. This was created in order for the citizens to be informed about any policies or general information about what is going on with the government.
The U.S. Department of Justice is the administrative power behind the FOIA. This policy is supposed to benefit citizens because it is supposed to allow them to access information that will keep them informed and up to date with happenings in the government. There are, however, some information that is not made public, such as things that claim to compromise national security or personal privacy. To me, this means that whatever they deem to be a “threat to national security” can be kept hidden from public view. That doesn’t sound very convincing about its “open access” claims.
