First, the judge sentenced him, not Ms. Perlow.  While he has multiple convictions, they are all non person crimes.  His only felony is possession of heroin, his property crimes are all misdemeanors.  The vast majority of people do not want to send people to prison for property crimes of certain levels.  Unfortunately my crystal ball doesn't predict the future, but maybe yours does.  He could have spent 3 months, 6 months, or 9 months in jail, and murdered this woman, and you people would still say he didn't spend enough time, and it's Perlow's fault.
