Cincinnati ? Nearly a year after the fatal police shooting of an unarmed black man set off several nights of riots, Cincinnati’s leaders Wednesday reached tentative agreement on sweeping changes in the police department and settlement of a racial profiling lawsuit.

The 60-page agreement, which capped marathon talks between police, city leaders, community groups and the U.S. Justice Department, could provide a model for other cities under acute racial stress. But it won’t end a boycott of Cincinnati’s downtown hotels, restaurants and entertainment venues by local black organizations.

If approved as written, the pact would restrict the use of police dogs and chemical irritants, improve the investigation of citizen complaints, enhance police interaction with community groups and set clear guidelines to govern the use of force on suspects.

“This will be the most comprehensive police-community agreement in the country. When fully implemented, it will change the way policing occurs in Cincinnati,” said Scott Greenwood, general counsel for the Ohio American Civil Liberties Union, which filed the profiling lawsuit.

“This is a historic moment for Cincinnati,” Cincinnati Mayor Charlie Luken said. “I strongly believe both agreements will significantly reduce crime and improve police-community relations.”

The Rev. Damon Lynch III, a black minister who helped negotiate the agreement, called it a “monumental first step” toward racial healing. But Lynch, one of the boycott’s organizers, said that because the tentative agreement fails to address pressing economic needs for blacks, “the boycott will go on even when this agreement is signed, sealed and delivered.”

Julie Harrison Calvert, a spokesman for the Greater Cincinnati Convention and Visitors Bureau, which has been courting tourism in spite of the boycott, called Lynch’s comments “extremely disappointing.”

“It’s interesting that the ones who are so quick to criticize the city for not changing are the first to look the other way when progress is being made,” she said.

Cincinnati’s riots began last April when Timothy Thomas, 19, was shot and killed while running from police. Thomas, who was wanted on numerous misdemeanor charges, was unarmed. He was the 15th black man to die in a confrontation with Cincinnati police since 1995.
