No. 1 I want to stop riots (Ki baek)
Sports violence is a big problem, so we must prevent that.
First, enforcing crowd control is a very important thing. Police need to pressure rioters and troublemakers and make them more careful. If they do not do obey the police, they will be arrested. Also, prohibit alcohol is effective, too. Alcohol makes people too brave; they can not understand what is happening and they lose their inhibitions. Finally, I think banning alcohol when people are watching a big game is very effective too to prevent riots. If we can control ourself, it is not necessary. But, it is true about effective prevent riots. When we be careful, we can enjoy a big game. it is up to you.
