A Chicago Police officer was sentenced Thursday to 40 months in prison for beating a man shackled to a wheelchair in a hospital four years ago.

William Cozzi stood expressionless as U.S. District Judge Blanche Manning imposed the sentence Thursday.

The case could have an impact on the whole police department, reports CBS station WBBM-TV in Chicago.

"In my opinion, this prosecution was brought by Superintendent Weis was misguided and vindictive," said Cozzi defense attorney Terry Gillespie.
