Episode three *major spoiler*

Well, I warned you, there are major spoilers in this message so if you read it and haven't seen the show, you have no one to blame but yourself.

I just finished watching episode three of the ghost squad. I've read some messages where people either say that they're shocked or find it funny. People find it shocking because those are a couple of teenage girls violently beating up a man, so bad that he's in a coma. Others find this funny because they think it's funny to see little teenage girls screaming swears and beating up a guy. I personally don't.
I think that episode was had a very important message. Violent like that is getting more common everyday. Kids are bored and out of controle. I live in Iceland and violence like this is very common here. There are gangs of kids here, some not a day older than 13 (most of them ages 15-19 though) that go around, beating up random people. Just a few days ago there was a report about a kid who got his skull broken just because he was unlucky to walk past them. Not too long ago, one of my friend got beaten up. The reason: she was at a prom, some guys started fighting for something (a girl I think, but I'm not quite sure), things started to rough up, more people started fighting, she realized this was going to be trouble so she was going to go outside. On her way outside a boy grabbed her and punched her in the face.
I define that there are two types of kids that are mostly responseble for those things:
1. Kids who have parents who don't care about them. The police here can't do anything about those kids, just give them a warning and report it to the parents. If the parents don't care, they don't do anything about it. The kids get the message that they can't be touched, nothing can harm them and so they continue, acting more and more violently, pushing the limits until they can be pushed no further.
2. Spoiled kids. Their parents think they're perfect so that everytime when they do something wrong, their parents always protect them 'no, my child can't be doing anything wrong,' or they try to find an excuse 'he's not bullying him. this is just what kids do, rough around.' The kids feel that no matter what they do, mommy and daddy will always get them out of the pickle so they keep on pushing the limit.
I am so sick and tired of this. I go to the same class as a boy who beat up a boy so he's blind on one eye. The police didn't do anything to him, they can't do anything. They can't arrest him, they can't make him do social service, they can't do sh*t. It's horrible to be in class with him. And I just named one of them, there are more. At least half of the boys in my class have been responseble for violent acts (I'm talking serious, not just giving someone a black eye, threatining people with weapons, beating people so badly that their ribs are broken. Sometimes when I'm in class I'm really scared. Thinking 'what if something I say will tick them off. Will I walk out of this room blind on one eye or with broken ribs. Once two boys started fighting. The teacher wasn't in the room, I knew the he would be mad when he'd come so I told them to knock it off and sit down. I heard something getting thrown so I put my hand in front of my face in self defence. I felt pain in my hand so I checked to see what had happened. There was a compasses stabbed into my hand. And that's just one example. Nothing was done, when the teacher came in he just told me that I was allowed to go to the bathroom to whipe the blood off my hand (I had already ripped the compasses from my hand). And that's just one example.
I have gotten into a few fights myself (not serious ones) when I was younger. My parents went mental. They made the message very clear that this was the kind of behaviour which wasn't tolerated, and since they've preached over me I realized that what I did was wrong. Parents have to at least try to be in controle of their kids or violent acts will just get more common, even more common than they're now!
Anyone agree with me?
