SECURITY EXPERT: ‘POLICE DID AN EXCELLENT JOB’

One school security expert, Jason Russell, praised the police response during the shooting. Russell is a former Secret Service officer and now founder of a security consultant firm.

“They did an excellent job of making sure that they not only got everyone safe but also being able to find that suspect fairly quickly,” Russell said.

He said he listened to the scanner as the night unfolded. He said he was impressed with the dispatchers as they handled several 911 calls and sent officers to where they needed to be on a large campus, and he heard officers volunteering to go to different locations to make sure students were safe.

“I thought the police did an excellent job,” he said.

Russell said he didn’t think there were any gaps in security at the campus.

“These situations happen all the time, we’re becoming desensitized to it. Unfortunately I think every place that has an incident has to look and have their security examined,” he said. “It doesn’t appear that there was any lapse or gaps in security. These were publicly open buildings and you have an attacker who decided to take advantage of publicly open spaces.”

“I think that Michigan State University has done a good job of setting up safety and security,” he later added.

Russell’s daughter attends MSU. He said she is safe and came home on Tuesday.

“Obviously a lot of mixed emotions. We’re happy to have her home and safe, and our hearts and our prayers go out to every family that’s affected by this tragedy,” he said.

The university has done a good job of offering mental health support, and parents should pay attention to their kids and get them help if they need, he said.

“Thar’s nothing wrong with asking for helping and making sure to get somebody to talk to about these situations,” Russell said.
