I went back and completed the article, as I have some business interests in the HC market. I would suggest the reporter was a little bit under informed in choosing the words "terrorism drills", as the more probable likelihood would better fit under "workplace violence". That being said, the ICU is probably a "higher potential drama" department than say the cardiovascular outpatient area, where rival gang bangers get to be treated side by side, interspersed with other end of life scenarios.

What is interesting is the COO tossed the Security director under the bus almost as quickly as he would have tossed the Security Director under the bus if a law suit emerged that was built around an incident that illustrated a lack of drilling as the root cause of a poor incident outcome.
