Replying to Out of control party

Last saturday i was at a party where there ended up being a ton of kids getting hyped up on coke, a long with a bunch of hood people as well (not a good thing). I was just looking to have a good time with some friends and get drunk. When i was leaving this 57 year old drunk neighbor comes over to these kids and starts saying that all the girls are whores and sluts. Three 18 year old kids amped on coke beat the fucking shit out of this guy. They punch the fuck out of him rip out the guys hair then kick him when he is on the ground, all three of them. When they are finally done this guy has pools of blood around him on the pavement and was not moving. my friend called 911 immediately and we go over to the guy and see that he is still breathing and was conscious but had a large gash in his head and face with blood soaked in his shirt and massive pools of blood around him. He grabs my friends arm smearing blood all over it and mumbled something. We tell him medics are coming and hes gonna be ok. Frankly it looked far from ok. The medics arrive and take this guy to the hospital where he is in critical condition with a broken back and he has a chance of dying from these injuries. These kids are know in jail where they fucking belong. fuck parties with coke and dumb hood people who can't control them selves.
