"I'd advise these people to get treatment for PTSD [post-traumatic stress disorder]," said Pratt, referring to the network's employees who were at work during the incident.
"If they don't get proper treatment, they will most likely experience nightmares, intrusive thoughts and flashbacks," he said.
Lieberman agreed, and said while the employees probably wouldn't experience long-term effects from the standoff, they need to address what happened.
"The degree they're affected," he said, "would depend on how long [the hostages] were held, how close [the employees] were to the perpetrator and their individual vulnerability to stress-induced mental disturbance."
