PHILADELPHIA — The co-director of a Pennsylvania company that provided intelligence bulletins to the state that outraged Gov. Ed Rendell and prompted his apologies to peaceful protest groups says that posting the bulletins online increases the risk of harm to potential targets.

In a memo obtained by The Associated Press, Michael Perelman of the Philadelphia-based Institute of Terrorism Research and Response expresses concern that the state's release of the bulletins last week "has increased the threat to Pennsylvania's infrastructure — including its most vulnerable component, students studying abroad."

The memo, sent to Pennsylvania Homeland Security Director James Powers Jr., urges Powers to pull the PA Intelligence Bulletin issues off the Internet "until they can be carefully reviewed and redacted of all information that provides intelligence to those who would do harm to American citizens, the Commonwealth, and its people." Perelman told the AP on Sunday that he did not authorize distribution of the memo but he confirmed its contents.
