Lamphere High School in Madison Heights was placed on lockdown after a man was seen carrying a rifle near the school. 7 Action News has obtained video of the man walking down 13 Mile Road and in front of Lamphere High School in Madison Heights with that rifle strapped on his back. Police say the man identified himself as an Open Carry advocate who was exercising his rights. In Michigan it is legal to carry either a handgun in a holster or a long gun that is not pointed in a threatening way in public. Madison Heights Police made sure the man did not intend to enter the school and let him continue walking. They did not ask his name or destination. They’ve had confrontations with gun advocates in the past who have recorded their incidents and posted them online.
