Supernatural stuff aside, it would be a matter of comparing violent crime per capita (taking into account visitors). Then also taking into account suicides (taking those out of the equation since it seems to be also a suicide destination). The crime rate might still be lower. These shows would provide a very skewed portrayal of violent crime. I mean, also what type of crime, the park didn’t have a whole chain of banks swindled by a guy that now has to pay a couple thousand dollars per month for 1000 years (not feeling like looking up the actual number).
