North Carolina's top law enforcement officer joined education officials today in announcing a new and thorough review of campus security, two days after the Virginia Tech massacre.

Attorney General Roy Cooper says he'll launch a task force to analyze safety protocols on the state's higher education campuses.

School administrators and security officers from around the state have already started a new assessment.

At North Carolina State, dorms are permanently locked and residents need a key or a card to enter. The school also uses e-mail and faculty liaisons in all buildings to distribute emergency information across its two-thousand-acre campus.

Officials are considering a reverse 9-1-1 system.

Wake Forest University has gates that can quickly halt vehicle access to campus. East Carolina University can lock some of its campus buildings with the push of a button.
