The policy, which applies to all boys and girls sports, starts Monday.
CPS (Chicago Public Schools) officials have also met with Chicago Police district commanders, alerting them of the basketball schedule for the rest of the season.
All varsity start times have been moved to 4 p.m. to try to stop the violent brawls marking crowd behavior at several games.
Davis wouldn't specify which schools the policy targets but said most CPS basketball games are incident-free. Michael Vaughn, CPS spokesman, said "everyone knows where the issues are" when asked which schools were affected.
There are more than 5,000 students on CPS basketball teams. Davis said student athletes have higher attendance and graduation rates and fewer disciplinary incidents than other students.
"I don't think this is a sports problem. I think it's a community problem," he said. He later said he thinks the incidents this year stemmed from "pre-existing conflicts in the community."
Two incidents happened outside the schools after games. The other two were fights started by fans.
Recent violence courtside and outside CPS basketball games has forced the school system to crack down on security:
Jan. 9 Five teenage boys were shot outside Dunbar Vocational Career Academy after a Friday night game against Hope College Prep High School.
Jan. 20 A game between Simeon Career Academy and Bogan Computer Technical High School ended with 5:55 left after a fight erupted in the stands.
Jan. 20 Jermaine Winfield, a North Lawndale College Prep senior on the basketball team, was shot in the thigh outside Collins High School following a game. Winfield was trying to break up a fight.
Jan. 22 Two teenage girls reportedly started an on-court brawl after North Lawndale College Prep's win over Marshall Metro High School. Security escorted players into the locker room for safety.
What we know about Chicago,
Races in Chicago:
(Total can be greater than 100% because Hispanics could be counted in other races)
- Black (36.8%)
- White Non-Hispanic (31.3%)
- Hispanic (26.0%)
- Other race (13.6%)
- Two or more races (2.9%)
- Chinese (1.1%)
- Filipino (1.0%)
- Asian Indian (0.9%)
- American Indian (0.7%)
- Other Asian (0.5%)
And since the census counts North African and Middle-Eastern groups as "white non-hispanic", we can conclude that Chicago is somewhere in the neighborhood of 20 to 25% White.
Diversity; making every city, town and neighborhood into a little Palestine.
