An Allegheny County judge on Monday heard more arguments about releasing documents related to police conduct during last year's G-20 economic summit.

The Pittsburgh Citizen Police Review Board says it needs the documents to complete an investigation of incidents that occurred during the Sept. 24-25 summit of world leaders.

Attorneys representing city police Chief Nate Harper say the board doesn't have the authority to review the documents because the request doesn't stem from individual complaints, and some of the information
could jeopardize national security.

Common Pleas Senior Judge R. Stanton Wettick Jr. did not make a ruling in the case. He said he has a "legal issue to ponder" and is unsure when he will decide.

Elizabeth Pittinger, executive director of the board, said it asked city and police officials in November for a roster of officers who worked the event, their locations and training records, and incident
and arrest reports. The board plans to use the information to evaluate
the tactics officers used for crowd control and the policies and
procedures of the police bureau, she said.

Police made nearly 200 arrests as thousands of protesters marched the streets. Protesters clashed with police in Lawrenceville and Oakland, causing some riots and about $50,000 in property damage. The
review board received 12 sworn complaints against officers and 73
notifications that people intended to file complaints, Pittinger said.
