Active attacker survival tips from a national security expert

Run, hide and fight were some of the first words Ohio State University police tweeted Monday morning, alerting students and staff an active and dangerous situation was unfolding on campus.

The Department of Homeland Security developed the strategy for people involved in active shooter situations, which is what OSU police first reported.

"(Abdul Razak Ali Artan) didn't have a gun, but he still had the same intention to hurt or kill people, and his weapons of choice could easily of done that," said national security expert Timothy Dimoff.

The violence and chaos that broke out on OSU's campus was quickly brought under control, thanks to a fast response from police officers and the countless hours of training they've gone through over the years.

"(Monday) showed me that the training was really effective and it prepared them," said Dimoff.

Police said Artan ran his car into people on campus then used a butchers knife to stab other people walking near Watts Lab. It took only moments for police to respond to the scene.
