After the attacks on the World Trade Center on September 11, 2001, the institute formed the Center for Tactical Counterterrorism (CTCT), later renamed the Center for Policing Terrorism (CPT). The group was created at the request of the NYPD, to provide research into new policing techniques with the goal of retraining officers to become "first preventers" to future mass-casualty attacks. Led by executive director R.P. Eddy, the CTCT held a conference with highly regarded counterterrorism experts in the world and developed a strategy to transform the NYPD's approach to urban counterterrorism by blending intelligence gathering and analysis with traditional policing. One of the most visible components of this new approach was the overseas liaison program, which placed NYPD officers with police departments in foreign countries for the purposes of intelligence gathering, relationship building, and information sharing. Eddy brought on board Tim Connors, a West Point and Notre Dame Law School graduate, to oversee the day-to-day operations of the CTCT. The CTCT began publishing reports and white papers on intelligence fusion centers, local counterterrorism strategies, and intelligence-led policing. With the research assistance of institute staffers Mark Riebling and Pete Patton, the center produced rapid-response briefings on major terrorist attacks around the world and presented them at weekly meetings with the Counterterrorism Bureau. The institute's counterterrorism strategy also built upon Broken Windows and CompStat policing models by training police in problem-solving techniques, data analysis, and order maintenance. In January 2005, the CTCT cautioned against the construction of a new United Nations structure over the Queens Midtown Tunnel, which would have increased the value of the tunnel as a potential terrorist target. CTCT, and later CPT, continued publishing research until 2008 when it was absorbed into National Consortium for Advanced Policing.
