Sure. Just stand there and do nothing.
Well, that's exactly what you did. Right?
Actually, I argued with my boyfriend about whether we should do anything while the guy got his ass kicked, then abandoned the guy at the fire station. Then I went and got my glasses so I could see that he'd healed up after a year, you fucking coward.
Unless you are prepared to offer advice on a gun brand, model, caliber, and ammunition, you're a waste of ones and zeros and an instigating piece of shit.
BTW: My neighbor's out of the hospital with four broken vertebral processes and a chipped eye socket, a spectacular black eye, huge bruises across his back, swelling on the back of his head and neck, plus a bit finger he got while head-locking one of the fuckers. I told him I felt bad that I hadn't gotten out there sooner, in glasses and boxers, but he figures I might have saved his life, and I at least kept him from getting beat worse.
