New data shows that on average the NYPD made four arrests and issued seven summonses a day in city public schools in 2011.



The New York Civil Liberties Union analysis was released Tuesday under a new City Council law requiring documentation and disclosure of school safety data.



More than 95 percent of the 882 arrests involved blacks or Latinos.



About 75 percent of the incidents involved males; about 20 percent were children between 11 and 14.



Most of the incidents involved disorderly conduct and harassment.



The NYCLU said police shouldn't be in the business of school discipline.



The NYPD says school safety agents and police officers do good work in an unbiased manner.
