Crime happens, even in national parks, national forests, and other public lands. There are murders, thefts, robberies and all sorts of crime that we'd hope to escape by heading into the kingdom of public lands. It can be hard to accept that national parks are not immune from criminals and crimes. Just this past Fourth of July there was a horrific incident in Yellowstone National Park when a concessions employees armed with an automatic rifle threatened to go on a killing spree. Law enforcement rangers who responded prevented that from happening, killing the man in the process, but it really underscored the reality that parks are not immune from crime. To learn more about "crime off the grid," we're joined today by Tara Ross and Nancy Martinz, former law enforcement rangers in Yellowstone who these days work to educate the public about crime on public lands via their podcast, Crime off the Grid.
