Absolutely. Because here, guns are not as common as they are in the US so police officers would most probably think the gun is fake.Let's take this same 12yo kid, with the same gun, with the same complaints about waving it around in the park, responds to police requests to raise hands by reaching into his belt and drop him in France. Are your police so trained as to assess the situation any differently? Would Japanese handle the situation differently because citizens don't have handguns?
They may come armed and ready to use deadly force, as BioDefenseGrad said, but they would not shoot so fast at a kid who's not even pointing the gun ot them, who's not even holding the gun in his hand
But once again and as I said a few post before in this topic, this is all about the absence of gun laws in America
