Student stabbed at Saints Stanilaus High School over YuGiOh cards.

It was reported in the news that a student from Saints Stanilaus High School was stabbed in the school compound early one night whilst playing with some collectible cards that are popular with kids (and some adults).

It was said that the boys were playing a game with the cards when a dispute occurred resulting in one boy being stabbed in his back and subsequently needing 5 stitches at a city hospital.

Now here's the thing. This incident occurred close to 7pm, I want to know why those kids were even allowed to be on the premises at that time considering that school is dismissed at 3. They had earlier left the school to attend lessons only to return later to play with these cards. What's the matter, are students not privileged to get homework anymore? and don't parents worry anymore when their kids aren't home by the time the sun goes down?

The headmistress of this school or maybe the ministry of education should ban the use of yugioh cards in schools. Children are there to learn not to duel. Dueling with these cards are a big thing in many schools and it should be rooted out and this regrettable incident as Saints just proves it.
