My brother stays with me and is on federal parole. Recently, I left an airsoft (spring type very weak) air pistol out in a common area of my house and my brothers parole officer happened to come by noticed it,confiscated it, and became very disrespectful towards me. Unlike my brother I have never had any trouble with the law. Based upon the parole officers action I believe that it is possible that he will return and want to do some sort of search of the home. My question is what legal limitations are there to a search of this kind e.g. (the whole house, my brothers bedroom, common area's etc). I have never broken the law and have nothing to hide, but don't relish the idea of marshals coming into my home and tossing it. Thanks in advance for your response.
