D.C. Mayor Marion Barry and Police Chief Maurice Turner yesterday formally unveiled a 15-point program to fight crime by calling upon -- and rewarding -- the public for help.

The program, which is called Police and Citizens Together (PACT), features cash rewards for turning in drug dealers, expansion of the Reserve Officer program and compilation of a list of the city's 10 most wanted criminal suspects. Most parts of the program went into effect yesterday.

Barry introduced the progam, details of which were disclosed during the summer, as "my new crime-fighting mission."

According to Turner, citizens can get cash awards in two ways: between $1,000 and $25,000 will be awarded for information that leads to the arrest and indictment of major drug dealers, and $1,000 will be awarded for information that leads to the arrest of a fugitive appearing on the "10 most wanted" list.

Turner also said the department will recruit about 600 new members for the Police Reserve Corps, a group of unarmed volunteers who wear police uniforms and assist officers on the street. Police officials said the city will study the possibility of arming some reservists. A police spokesman said questions of training and liability need to be explored and resolved.

Other parts of the campaign include drug education for students, an expansion of the Neighborhood Watch program and cash awards to cabdrivers who alert police to crimes in progress.

Barry called his anticrime program, first announced in 1981, "very, very successful. We have become a model for jurisdictions all over the world who want to develop creative efforts between citizens and police."
