If you honestly think you're going to defend yourself, unarmed, against a guy twenty feet away, holding a gun that's pointed straight at you, his eyes on you the whole time for the slightest movement, then you sir, are delusional. This isn't CoD or some fantasy world. If you reach for something, you're dead. If you move, you're dead. If you try to distract him and move, more than likely, YOU'RE DEAD. Heroes are real, but superheroes are not. If you think you're going to move like Flash and disarm him, or pull out your batarang like Batman, you're going to wind up riddled with holes, on a street or in a ditch. So again, good luck with that buddy.
