No, it's not part of the Smithsonian, but that doesn't mean that the National Museum of Crime and Punishment isn't worth a visit during your next DC trip. Located in Penn Quarter, this three-floor, 25,000 square foot attraction is host to hundreds of interactive exhibits and displays which let you try out everything from CSI-style forensics to high-speed chases, as well as a unique collection of crime-related artifacts and memorabilia, including a recreation of Wild Bill Hickok's revolver, John Gacy's artbox, and John Dillinger's 1933 Hudson.
