The FOIA round-up hits hard this week as reporters find thousands of records showing startling police use of force, lead infested army housing ignored for years and Environmental Protection Agency officials neglecting clean-up in cancer cluster communities.

When the Federal Bureau of Investigation’s FOIA office in the Records Management Division prepares to release a file that it deems significant, newsworthy or controversial, it issues what’s known as a High Visibility Memoranda. These memos, circulated to different parts of the Bureau and often to the Director’s Office as well as outside agencies, outline the proposed releases and their possible fallout. A recent release of over 500 pages of these memos serves as a list of files for FOIA requesters to file new requests for so the files can be published online, as well as showing government reactions to the requests themselves.

What’s considered public record or not is not a new debate. But the increasing prevalence of social media use amongst government agencies and officials, such as Twitter, brings up a new debate: If you delete social media posts on an official account, is it a violation of public records laws?
