Maryland’s higher education institutions are waiting for more details about the Virginia Tech shooting that left 33 dead Monday before reviewing their security measures, but vowed changes if needed.

On Monday, a student identified as Cho Seung-hui, 23, killed two in an early morning shooting in a dormitory at the Blacksburg, Va., campus and then two hours later opened fire in a lecture hall and classrooms before committing suicide. In total, 33 died and dozens were wounded, in the deadliest shooting in U.S. history.

All schools have plans in place for catastrophes, said Deb Moriarty, vice president of student affairs at Towson University. “Everything looks good on paper until you’re in the middle of a crisis,” Moriarty said. “It all comes down to a human judgment call.”

Monday’s shooting began shortly after 7 a.m. when two people were found murdered in a dormitory. However, the university administration did not send an e-mail warning to students until 9:26 a.m., the Associated Press reported.

By that time, the shootings in Norris Hall had begun.

“Communication is always a problem,” Salisbury University Police Chief Ed Lashley said, adding a plan can be great, but with poor communication it will always have a weak link.

“Every university will take this somber opportunity to learn from any mistakes and incorporate positives into their own plans,” Lashley said.

The Salisbury University Police have been working closely with local sheriff’s departments to perfect an active-shooter plan and hope to have an on-campus test in the coming weeks, Lashley said.

Salisbury also has a hostile-intruder policy, addressing hostage situations in both resident and non-resident halls, he said. Under this plan, the police are the first responders and identify the magnitude of the situation.

A shooting would generally lead to a “category-three” situation, meaning a communications command center would be set up, the university would be locked down and students moved where necessary, he said.

The Virginia Tech campus of more than 25,000 full-time students is no stranger to lockdowns. In August 2006, there was a manhunt for an escaped inmate that led to a campus shutdown and sent students to their dorms.

On Monday however, the campus was not locked down following notification of the two shootings in the dormitory.

“We don’t know what happened at Virginia Tech,” said Cathy Atwell spokeswoman for the University of Maryland, College Park, Department of Public Safety, “there are no lessons learned.”

Maryland’s emergency plan includes mass e-mail and voice mail notification and warning sirens. The police also have the ability to lock all buildings from a central location if need be.

The full emergency plan is posted on the University’s Web site, but Atwell said nothing will be discussed as far as changes go until all the information becomes known.

Schools don’t want to “create a prison fortress,” Moriarty said. They need to rely on good policy, prevention efforts and hope.

Towson’s campus emergency plan involves the coordination of dozens of units, which are currently reviewing their protocol individually. They will all meet later this week once more information becomes known, Moriarty said.
