This is the first in a series of podcasts American City & County will produce leading up to the 10-year anniversary of the Sept. 11 terrorist attacks in New York and Washington.

When terrorists struck New York City nearly 10 years ago, Capt. Stephen Serrao was serving in the New Jersey State Police (NJSP) Intelligence Analysis Unit. He later went on to become the NJSP counterterrorism bureau chief, and he now serves as director of Law Enforcement Solutions on the Memex Solutions Team at Cary, N.C.-based SAS.

Serrao spoke with American City & County about improvements in law enforcement and homeland security technology and procedures since the attacks, and what remains to be done as the 10-year anniversary of 9/11 approaches.
