Youth Gangs
are gangs a danger to the school

Yes because when a gang member is on a school and has a fight with someone, the gang will come to kill him/her. That can lead to that students don’t feel safe anymore because they know when they do something that the gang member doesn’t like, the gang will come to the school and fight of kill him.
Also the rest of the students will be concerned in the gang life. When students know the gang member and they see him/her outside, they will talk with him/her. The rest of the gang will join and that can lead to more. Like they get friends and the student will join the gang also.
