The ruling means that people in Michigan who choose to exercise this constitutional right are now subject to being stopped by law enforcement for engaging in a completely lawful activity.
Officers detained Johann Deffert in early 2013. He was walking down the sidewalk with a holstered FNP-45 pistol, after receiving a 9-1-1 call from a woman who spotted Deffert with the open carried, but holstered, handgun on his person.
The dispatcher initially informed the caller that Michigan is an open carry state. However, the woman subsequently explained that she found Deffert's presence alarming, due in part to his wearing of camouflage, although she admitted that he wasn't threatening anyone. Somehow the dispatcher made the decision that someone engaging in a completely legal activity, as earlier in the call noted by the dispatcher, should now be inspected by police, due to caller saying they found wearing camo disturbing.
