Yes, I know, the wheels grind slowly, ...

FBI hopes grainy video will help solve 25-year-old $500 million art heist

Federal investigators in Boston on Thursday released 25-year-old surveillance video showing a security guard admitting a man to the Isabella Stewart Gardner Museum the night before it was robbed of $500 million worth of art in the largest such heist in U.S. history.

The six-minute, 40-second video shows a white man, wearing glasses and apparently in his 50s or 60s, being let in by the guard through a rear entrance to the museum shortly after midnight on March 17, 1990, about 24 hours before the heist.

The (short) article doesn't mention why the FBI decided the time had finally come to release the video, nor why that time couldn't have come sooner.
