I believe making the public more aware of possible terrorist and/or terrorist threats will assist budget and personnel strapped law enforcement agencies to leverage off the public sector.
Shows like, "Americas Most Wanted", have assisted law enforcement in catching criminals. Request you explore using this type of medium to let people know, you need help.
Other Public awareness programs are: Crime Stoppers (which offer awards), tiplines, and Billboards announcements.
Putting out information vice having them search for information, will keep the public informed plus, make people more aware of possible terrorism/crime.
