The school had no choice but to expell this rotten student,The expulsion though was not for murder bu for minor offences like pulling the fire alarm. Expulsion is severe as it prevents enrollment into any college, therefore ending his professional life. I recommend that expulsion is not final but allows a second chance to get at graduation later on.

US: The country which loves its guns more than it loves its children.

Miniature technology to prevent from this type of shooting spreed and knife crime. America can talk to their friend Israel how they manage to stop the missiles flying from Gaza.

like in previous cases, see Columbine he was mistreated and wanted revenge

Obviously this killer was harassed in this school by the students by the way he looks, etc. And this was his reaction - getting revenge against those that made fun of the way he looked - big ears.

And then, of course, the issue of guns and the real easy access to them.
It's time people started to take security seriously and to understand that your words are like bullets.

Mark sherry says it was an assault rifle. I thought it was a semi-auto rifle. If so, then it's not an assault rifle. Assault rifles are full-auto capable. That means semi-autos are not assault rifles. Stupid people like to talk and talk and talk without knowledge. Now they can add a little knowledge to their stupidity.
