LindsayLindsay Lohan isn't a popular person to defend. In fact, her sometimes bizarre behavior and seeming disregard for the law make it downright impossible. And while many were happy to see the long arm of the law finally come down hard on the actress, Lohan's sentence seems particularly harsh -- well, part of it anyway.

On Tuesday, Lohan was sentenced to 90 days in jail and a 90-day inpatient rehabilitation program. The actress will likely serve approximately 23 days behind bars because, according to Los Angeles Sheriff's Department spokesperson Steve Whitmore, female inmates in custody for nonviolent crimes generally serve about 25 percent of their sentence. Few would argue that Lohan doesn't deserve the jail time; after all, any other person in her situation would have been sentenced to the same.

What's more interesting here is the required stint in rehab. This addition to Lohan's sentence is not especially notable because the actress was hit with it, but rather because others in the exact same situation have not been.
