H&FJ Crime-Fighting Division
It was not a dark, stormy night at the H&FJ offices, and she was not a dame in a red dress who spelled trouble with a capital T. It was last Friday afternoon, and the caller was Bill Bastone, founder and editor of The Smoking Gun, with a question about forensic typography.
The story begins with last week's report by the Los Angeles Times that murdered rapper Tupac Shakur was assassinated by associates of Sean "Diddy" Combs. The Times appears to have relied heavily on a set of FBI reports — 302s, in the argot — which cannot be found in the FBI's own files. This morning, The Smoking Gun suggests that these may be the work of an accomplished document forger named James Sabatino, who conducted his hoax from within the walls of the Allenwood Federal Correctional Complex in Pennsylvania.
We're not experts in forensic typography or document authentication, but were able to point TSG's specialists toward one subtle typographic clue. To untrained eyes including ours, the three 302s look like genuine bureaucratic dross: form elements are typeset in a proportionally-spaced font that appears to be Times Roman, and the body of each document is filled in with a typewriter. (The occasional overstruck letter, as well as some very erratic line endings, suggest a typewriter rather than a word processor; never mind that the Bureau stopped using typewriters "about 30 years ago," according to an FBI supervisor.)
But a telltale gaffe appears at the top of one document, in which the date is rendered in the proportionally-spaced font. The "advance width" of the periods are demonstrably narrower than that of the numbers around them (typewriter periods are famously aloof from their neighbors), suggesting that at least this part of the document was prepared digitally — but only this part of the document, and only this one document from the set of three. The Smoking Gun has all three documents online: compare them here, here, and here. You owe me, Diddy. —JH
