People have been killed for not dropping their cell phone(weapon) when told to.
The officer has a bit of adrenalin pumping when he believes someone may be pointing a weapon at him.
I'd say paint it pink but the local gun shop has some very delicate pink handguns in their cases.
Probably the stickers or dots on the thing would make it look less like a weapon, but when the cop says
to drop it, that's a real good idea.
If you have it on the neckstrap, hold the strap, drop it and gently set it on the ground.
