In the 1920's, Belle Isle was a secret port for smuggling alcohol into the U.S. from Canada. The island was teeming with mobsters on little motor boats who brought liquor over by the jug-full.
Now that Belle Isle is a state park, alcohol is back to being outlawed, and the place is being patrolled by state police and the Department of Natural Resources.
Many Detroiters have complained that the police are unfairly targeting drivers on the island.
According to Joe Guillen of the Detroit Free Press, since becoming a state park earlier this year there have been about 500 arrests. Among those who were pulled over were Detroit's city clerk, and even the city's mayor Mike Duggan.
