At the core of the massive anticrime bill being considered by Congress is money to deploy tens of thousands of new police officers on the Nation's streets. While proponents of Federal involvement in community policing believe that adding officers will reduce crime and make officers a more familiar presence in their neighborhoods, opponents fear that Federal grant rules will reduce local agencies' flexibility and force them to devote scarce resources to a single crime prevention method. Community policing encompasses an attitude that challenges the organizational hierarchy of many police departments and calls for more interaction between citizens and police officers.
