Police and Communities - Evaluation of the COPS Program
Drs. Jeffrey Roth and Christopher Koper, joined by a multi-institutional group of researchers under the direction of Dr. Roth, conducted a multi-year assessment of the Community Oriented Policing Services (COPS) program, the federal government's $9 billion initiative (enacted in 1994) to add 100,000 police officers to America's communities and promote the philosophy of community policing.

Read their most recent reports (2002-2003) on the COPS program's impacts on the level and style of policing in the US.
