shooting by 18-year-old boy

On 11th, a 18-year-old boy was arrested on the suspicion of having shot 6 high school students when they got out of a school bus in Las Vegas, Nevada. The police are still pursuing another susoect. The police said that it seemed that this case is connected to a trouble over girl friends. I think that it is tottaly unacceptable to shoot people even if there is some trouble. These days there are a lot of people who take human's lives lightly.
