Ask Sergeant Natalie Altizer of the Greensboro Police Department about her best assignment in law enforcement, and she will tell you about VCAT. Altizer was the first female officer appointed to the North Carolina agency’s Violent Criminal Apprehension Team, a unit that works with state and federal officers to arrest Greensboro’s worst criminals. VCAT’s mission is to bring in murderers, armed robbers, rapists, and other serious threats to the community.
