About 15 years ago, a good friend of mine left the bureau, and went to work with the National Park Service as an criminal investigator. He worked Yellowstone, and several National Parks in California and Oregon. To hear him tell it, a major park that has hundreds of thousands of visitors a year is no different then a mid sized city. Murders, rapes, drugs, car accidents, its all there. The only difference is the occasional bear mauling, and the scenery is a lot nicer...
