your wrong, in many cases when they leave jail they have to report to a probation officer.  but not all do just depends on condition or release. The probation officer can also make them move out of any place they feel and they usually inspect where they are living and either approve or not, if not they have to find another place. Just because one is released from jail doesn't mean they are FREE. Some have numerous restrictions, unfortunately many probation officers have too many to look after.
