MINETA TRANSPORTATION INSTITUTE releases MTI Report 12-74 Detailing the following excerpts “In response to the threat that terrorists may attack anywhere, members of the public have been mobilized to bring suspicious behavior or objects to the attention of the authorities”. “Security measures should aim for a net security benefit. Increasing security in order to merely displace the risk from one target to another, while necessary in special circumstances, offers little net security benefit. This argues against disruptive and costly security efforts to protect public places”. “Nevertheless, security measures have demonstrable utility. They can create operational problems for would-be attackers; affect terrorist target selection; reduce terrorist effectiveness; uncover explosive devices; detect weapons; assist authorities in quickly diagnosing and responding to attacks; help to quickly identify and apprehend perpetrators, thereby preventing further planned attacks; and facilitate rapid removal of innocent individuals from harm’s way”. “Enlisting the public in security demonstrably works. One security measure that can be quantified and that appears to work in the area of surface-transportation security is enlisting staff and the public to call attention to suspicious behavior and objects.
