It took two rulings under the federal sentencing guidelines to spare police officer Justin Volpe life in prison for his assault on Abner Louima in a Brooklyn police station in 1997.

When the disgraced former police officer was led into Judge Eugene Nickerson’s Eastern District courtroom yesterday, he faced a presentence probation report that calculated a total offense level under the guidelines of 46. Anything at or above level 43 meant life in prison.
