Parole officer harassing my mom was removed and I was given new officer be he showed up without calling first

You've got to deal with it... they don't HAVE to make an appointment to get you enough time to get where you were supposed to be. Being convenient to you isn't part of parole. They can even drop by and go through wherever you are staying... without a warrant.

Part of your responsibility is to explain to your mother that if you give her home as your residence, she has to let POs in and as smoothy said, go through closets and drawers.
OR you can go back in. Parole is basically prison at home, because prisons are crowded and costly.
