I have POA for my brother he is in a nursing home now but has his home, He wants me to get stuff for him at his home. His X son in law lives there, I went to home and he let me in then when I said I am here to get stuff for my brother he called police. A policemen came and I showed papers but the policemen butt me out. two weeks later i took my brother to police so they know and again they wouldn't let me go in with my brother. what good is the POA??
