The claim: Michigan Nat'l Guard base has several confirmed detention camps, classic setup with high fences, razor wire, etc. Guard towers are very well-built, sturdy. Multiple compounds within larger enclosures. Facility deep within forest area.
What it really is: Using Google Maps I've taken a look around the area of the camp, and the only buildings that I can find that comes even relatively close to what resembles the claim are some private businesses and churches off base and some recreational areas.
