The police came to my house this morning at 5:30 A.M,  to arrest my son. He didn't have an arrest warrant or a search warrant. He came in search my house and took my son out of here. He went in his coat pocket and took his car keys and they drove off in his car. My property I have no trespassing signs out there, and private property signs, what I need to know were they in the wrong for doing this. They didn't find anything in my house, but they found a roach in my son's car at least that is what they said. They have him on an 100,000 bond. I need to know if there is anything I can do.
