Just after saying (one posting below) that the Tacoma News Tribune does tons of accountability reporting using public records, look what pops up in the next edition of the TNT. A story--made possible by public records--about jail guards in Pierce County racking up massive overtime. Excessive overtime is important to the public because tired workers might make unnecessary mistakes (like accidentally letting dangerous prisoners out of jail).
This TNT editorial from November 23, 2007 describes why too much overtime is a problem.
