All correctional officer should wear cameras just like police officer who working outside the jail

My brother is currently incarcerated and in his pass years he been treated like a animal and sexually harassed by correctional officer and beaten and the corrections officer lies claiming it never happened so my brother never have it fair out it and this doesn't just happens with my brother other things happen worse to other inmates that never gets proven like deaths in prison by correctional officer so I think that it's only right and for the safety for inmates at the end of the day these inmates are people are human just like you and me with rights not animals lock up and put away and forgotten and treated unfairly
