I noticed this scene while driving past on Sunday after visiting the Tashmoo Biergarten. There were four cars total, one State Police, one Sheriff, one Detroit Police car/ and a 'Highway Patrol' car. [Not sure what that means. Is it private security or is there actually a Highway Patrol vs. just State Police?] Any news or ideas on this? Paid protection for film makers or somebody got caught? My schedule did not permit time to inquire.

Things seemed calm and urban tourist-types seemed to walk around undeterred. Three cars did have their hatches open as can be seen in this image. Click the image for a larger view.
