Scary -Hospitals being targeted?

In a post from , Little Green Footballs I found out about an alarming developement. It seems hospitals in Boston, Detriot, Indiana, and two in New Jersey have recently been cased by people of "Middle Eastern descent". They wanted tours and patient information. The Homeland Security has issued warnings to hospitals about people posing as doctors or hospital inspectors. An ABC news station has further details.

I can only sepculate what this could mean. Are hospitals being targeted for attack or being assessed for their their ability to handle large casualities? One of the commentors at Little Green Footballs said that the terrorist who blew herself up at a Haifa pizza parlor had first cased a hospital. I will try find out more about that to see how accurate it is.
