“The big goal is  convincing people to take accountability for their own safety,” Beck said.

The conference was organized by Steve Nesbit, publisher of Campus Safety Magazine.

He told Lopez he could have filled the room with 900 delegates but the room only held 300.

Campus safety, of course, remains a hot-button topic around the nation.
