Accidental omissions

Usage examples of oversights.

This is not to say that criminals haven't been known to make numbskull oversights, such as leaving a driver's license at a crime scene or writing a "stick-up" note on a deposit slip that includes the bank robber's address and Social Security number.

One explanation for these oversights is that until now police and others dismissed the letters as hoaxes.

The possible moves being not only manifold but involute, the chances of such oversights are multiplied.
