Significance of crime scene/morgue photos

What is the significance of posting crime scene/morgue photos of the Tate/LaBianca victims? Do you think it is disrespectful to post such photos on blogs, websites & forums, or is it necessary for people that continue to study these cases? Some people have asked "why study a case that was solved over 40 years ago?" Was it truly solved? Do we really know what happened? I started thinking about this in great detail, and came to the conclusion that these awful, morbid, sickening photos MUST exist for several reasons, and morbid curiosity is not one of them.  If anything, the reason these photos are on the Internet for the world to see is so people don't forget the brutality of these murders. Also, matching up evidence seen in the crime scene photos with witness/perpetrator accounts can help researchers have a better understanding of the sequence of events. What do you think, dear readers? Should the crime scene/morgue photos be on the Internet, or should they be taken down? We'd love to hear your opinions on the matter!
