The FBI has provided these photos in response to USA Today investigative reporter Brad Heath's 2012 Freedom Of Information Act requests. They have been redacted under FOIA exemption (b)(6), to protect the personal privacy of FBI personnel. Presumably, the presence of Timon from Lion King was determined not to violate the privacy of the attendees at this retirement party.
There is no way to redact the FBI's inspiration, however. Color me impressed. [@bradheath via @AlJavieera]
