The shooting at Johns Hopkins and the threat at DePaul Health Center last week do raise some serious questions about security at hospitals.
Some hospitals, such as Barnes, have already gone to metal detectors, but security experts I spoke with believe preventing a determined gunman is a tall task. Instead, they believe responding to a crisis is the direction security seems to be heading.
And the CAD system, computer aided design, is the way St John's is going in. It's a system that can call up the exact vital information of any room or space in the medical center and send it directly to police and fire along with, in some cases, live video from security cameras.
Officials there spent about a year and a half combing through blueprints to compile this computer data base which is now being regarded as a security model, not only for hospitals in the area, but also around the country.
