Historical Violent History & Staff

My thesis has to deal with the violent history at historical sites & museums and how the staff at the museum handle it. Reactions to violent history can range from making it a gimmick to attempting not to mention it at all. Sometimes you only get the information on specific tours, sometimes it's played up for Halloween. Yet, what does a museum really gain from hiding this information, or on the opposite end, playing it up? I want to interview staff from 4 different historical places: The Lizzie Borden Bed & Breakfast, Antietam national park, Alcatraz, and The Sloss Furnaces. I want their take on this phenomenon and how they view the treatment of violent histories at their own sites. Do they have a hand in why they talk about it like they do? Do they think it should be different? And how does this attract visitors?
