A year after the Virginia Tech shootings, many students at the University of Maryland are still feeling reverberations.

This fact is made clear by statistics from University Police. More students are reporting suspicious behavior to police than before, and the text-message crime alert system they established by the university after the massacre is widely used. Students have reported nearly twice as many suspicious incidents to university police over the past year, said police Lt. Robert Mueck. Police estimated they received about eight calls of reported threats the week after the Virginia Tech shooting.

“More people were apt to report strange behavior [following the shooting],” said police spokesman Paul Dillon. “We definitely got a lot more calls.”

Dillon explained that if the department receives reports of threats, it launches an investigation to determine whether or not precautionary measures should be taken to protect others from the individual. Police can arrest the person, refer them to counseling, kick them off the campus or take no action, if police deem it necessary.

Although shootings are often unpredictable and difficult to prevent, reporting the warning signs to police makes their job much easier, Dillon said.

“We can’t completely prevent these things from happening. There are no absolutes,” Dillon said. “But if we get information, then we can take more actions to prevent it.”
