There are all kinds of degrees of threats too.
If they’re just going to stand in a line and chant stupid crap I would ignore them but if they’re singling out individuals and surrounding them etc, it has escalated to the point where displaying a weapon may be warranted.
I don’t know the laws in Michigan, but in Colorado and in Florida where I know CCW laws, firing a warning shot or drawing and not firing is not a permitted use of deadly force. The police may get away with it, but not commoners.
I don’t deny that this situation may be interpreted as a threat to life or great bodily injury to yourself or someonr=e there. IF this is the case, drawing and shooting is the only permissable action. Putting your hand on your gun without drawing is probably permissable. Stating that if the infraction does not stop you will shoot is probably permissable. If you draw there better be a reason that justifies shooting and if you don’t shoot that will mean that drawing was not justified. That does not mean that not shooting is always wrong. I had a home invasion long ago and heard someone outside, but did not know anything nefarious was up. Still, The person outside looked creepy through my peephole and I got my bedside gun. As I was coming back inside my livingroom this creep busted in the front door and was met with a 44 Special to the noggin. He turned and ran. If I had shot him right when he entered (in the front) it would have been legal self defense. If I shot him after he turned to run it would be murder. I wonder to this day that by not immediately shooting him, how many victims would be saved. As it was I did not shoot him even thouh he got inside and almost grabbed my throat. and the @##$% police department in Melbourne, FL said that If I filed a report that my gun would be confiscated for being at a crime scene. This dirtbag does not know how vetry close my revolver was to firing in double action mode. I declined to file a report. The police use tricks like this to show they are containing crime while they are not!
