Using brochures, public service announcements and meetings with community groups, iWATCH is designed to deliver concrete advice on how the public can follow the oft-repeated post-9/11 recommendation: "If you see something, say something." Program materials list nine types of suspicious behavior that should prompt people to call police and 12 kinds of places to look for it.
Among the indicators:
-If you smell chemicals or other fumes.
-If you see someone wearing clothes that are too big and too heavy for the season.
-If you see strangers asking about building security.
-If you see someone purchasing supplies or equipment that could be used to make bombs.
The important places to watch include: government buildings, mass gatherings, schools and public transportation.
The program also is designed to ease reporting by providing a dedicated toll-free phone number and Internet Web page through which the public can alert authorities. Los Angeles has already begun its toll-free number and planned to put its Web site up this weekend.
The Major Cities Chiefs Association, headed by Bratton and comprised of the chiefs of the 63 largest police departments in the United States and Canada, was expected to endorse iWATCH at its conference in Denver on Saturday as a model for all its communities.
"It's really just common sense types of things," Bratton said.
But American Civil Liberties Union policy counsel Mike German, a former FBI agent who worked on terrorism cases, said the indicators are all relatively common behaviors. And he suspects people will fall back on personal biases and preconceived stereotypes of what a terrorist looks like when making the decision to report someone to the police.
"That just plays into the negative elements of society and doesn't really help the situation," German said.
