An Eastern Michigan University student was walking on Pearl Street near the campus when a man approached him and attempted to grab his holstered handgun. The student was able to hold on to it until a second passerby came to his aid and the attacker fled the area.
Just a reminder that if you are going to open-carry, you need a very high-level of situational awareness, good retention skills, and a retention holster. This is not the first case, and won't be the last case, where an open-carry person was targeted for their firearm.
