First of all the Germans are proud that they don't need all this security stuff.....this will change sooner or later unfortunately.
Secondly this young guy was a kind of mobbed over years from his school mates and eventually he freaked completely out and did this unbelievable and not explainable bloodbath.

I agree, Video games are to a big degree responsible to implant ideas like that in troubled minds.
Long time ago when I was young you didn't hear about bad news like this one and our video games where more like pacman or so.

Germany has very strict rules regarding weapons, but unfortunately the father was a legal weapon holder and his son took one.....

For me it seems that the whole world gets more and more violent every year....robbery's and killings are daily in the news and everyone is getting used to it.

britexpat had a good point, what kind of childhood have this youngster in the nowadays?
Years ago parents used to play board or card games at the weekends with the children. Every day after school mom waited at home with food and checked that the homework is done.
Now children grow up with parents who work both and which are too tired after work to listen to children problems.....to keep them quiet they get a playstation....
Children between each other are not even able to talk to each other....unless it's in a chat room or through text messages.

I think we have to get used to a new kind of human beings over the next few generations.... :-(
