16-year-old Chris Medina, a student at Spring Valley High School (Clark County School District), went to watch a fight after school. The one-on-one battle didn't happen but an assault by an armed gang did. Chris beat an attacker off of a friend and dragged him into a nearby store. He was suspended and then expelled for being involved in a gang activity.

His father, Joseph Medina, is appealing the expulsion, maintaining his son is not a gang member but a hero. Some 280 classmates have signed a petition to bring Chris Medina back to school.

"My son risked his life to save the life of a student," said Joseph Medina, a real estate agent. "And this is how you're going to reward my kid? You're assuming that he's in a gang."

School officials said Chris Medina violated district regulations that prohibit students from causing physical injury and engaging in criminal gang activity.
The attacker was using a hammer to beat Chris's friend on the head and back. Chris was struck twice with the handle of the hammer before punching the gangster in the face and dragging his friend to safety in a retail store.

After the teenager hit Corado on the head, "the other Asians pulled out bats, pipes, crowbars and other things to do mass destruction. ... There was blood everywhere," one student wrote.

Principal Robert Gerye, who declined to comment on the incident, recommended his expulsion. The department director of pupil personnel services accepted the decision and recommended that Chris Medina attend Southwest Behavior High School.
...
Las Vegas Detective Mike Craig investigated the fight and wrote a letter on Chris Medina's behalf on April 20 stating, "Nothing within the scope of my investigation indicated that Christopher is involved or associated with a gang at this time."

He was a victim who was injured when he tried to prevent injury to his friend, wrote Craig, who did not return calls from the Review-Journal.
There were gangs involved, therefore it was a gang activity. Chris hit another student. Both of these demand expulsion under the district's zero tolerance policies. The actual circumstances don't matter a bit to the administrators.
