The London Metropolitan Police’s 150-year-old collection of crime artifacts, currently held in room 101 at New Scotland Yard, may open to the public in the near future if the recommendations of the Greater London Authority are followed. The GLA’s report says charging the public to view the collection could generate millions of pounds—for example, even a 90 day exhibition at could raise £4.5 million if visitors were charged £15 each. What exactly does the Met have in its possession that's worth £15 a pop? The collection, begun in 1874 as a teaching tool for rookie officers, and then called the Black Museum, contains weapons, death masks, and assorted criminal tools, as well as unique items such as the umbrella and ricin pellet used to assassinate Bulgarian dissident Georgi Markov in 1978, the pots serial killer Dennis Nilsen used to boil his victims, along with some sludgelike human remains, Jack the Ripper’s infamous “From Hell” letter, and another letter he sent to London’s Central News Agency in September 1888 in which he gloated, “I am down on whores and I shan’t quit ripping them till I do get buckled.” The Museum also contains artifacts from other serial killers, including John George Haigh, John Christie, and Dr. Neil Cream. We think the items should be displayed for their historical value, but the opening of the collection is by no means a foregone conclusion. Only time will tell if the GLA’s recommendations will be met.
