Dismissing a situation due to demographics may work for you, but it doesn't do much for the people who actually get affected by it.
I'm looking at it in a larger scale than my own sweet self.

And if there's anything I've learned in my life, it's don't always expect the worst, but always be prepared for it.
I can't tell you how many times its saved my ass.
If you assume that knowledge of consequence will, or ever has, stopped senseless violence, then you're living in an imaginary world. By people having the knowledge and means to protect themselves in case of a life threatening situation, it saves more lives than everyone sitting there thinking the criminals committing these crimes are suddenly going to have an attack of conscience.

This video is pretty old, surprising no one's brought it up before.

If it does happen to us, I don't think exposing ourselves to it first would make us any more prepared to incur a hammer to the face or a screwdriver to the eye. Things like this are just when the worst of luck strikes, and there's honestly really nothing you can do by that point.

^ I carry a loaded 9mm pistol in my car. If I'm unlucky enough to be in the wrong place at the wrong time, at least I have more of a chance that I'll survive a fucked up situation.

I'm just saying it's wise to know that there are people out there who do not value human life. If you value your own life, don't think the cops are always going to be there to save it.
We're ultimately responsible for our own safety no matter how many laws are in place... because there's always people who don't give a shit about laws and who definitely don't give a shit about you.

I watched 5-ish minutes of the video. For the most part it is very blurry, and after about 2 minutes it isn't really shocking. That may seem slightly corrupted and shallow, but after you see a guy get hit in the face with a hammer seeing him get hit 3 more times doesn't really add much horror, especially when you know he'll be dying in advance. The scary part isn't what you're actually seeing, but the mindset behind it, so the visualisation doesn't have much punch when you know what to expect.

It also helps when you watch Nothing Toxic all day long.
Man there's some crazy gore videos in there.

This one guy does a swan dive off a bridge or something, and lands face first on the edge of a cement ledge... splits his entire face in half. They show close ups, he's still breathing, and the doctors are trying to hold his face together.

I watched about 5 minutes of it. It was shocking yes but pretending that shit like this is a one of is naive to say the least. It's only because technology and communication has become readily available that more people are exposed to it. Genocide, war crimes, suicide etc has been going on since the year dot but it's easy to dismiss it when it's just word of mouth or the written word.

What disturbs me more is are things like this:

People uploading reactions of themselves watching the video, etc. It's making light of something like this and to think that this guy's kids might one day stumble upon it, you know?

These people are almost as f-cked up than the kid's that did it in the first place.

I don't normally wish this upon people, but I hope these individuals are getting raped, beaten to within an inch of their life, sent to the infirmary till they're healed up only to have it happen over and over again. I don't wish death upon them because that would be the easy way out for them. What I do wish is for every day to feel like hell, that every night they wish for death only to not have it come and instead the pain and misery that they inflicted on the victim and the victim's family. I'm just glad that they were taken out of society this early in life, I mean 21 victims for people that are younger than me is incredibly unnerving but I mean it could have been so much more if they weren't caught.

I watched it like 5 hours ago and eversince I cannot get that pictue of that guys bloddy face out of my head.

All i can think about is how he could have just been walking to town to by groceries for his family and just like that he was brutally tortured.

Yeah, take the above guy's advice and never watch it. I haven't and I don't plan to watch it.
