But in March, the Washington metropolitan police department admitted that the dozens of cameras it has had in place since 9/11 have so far netted zero arrests. What the surveillance cameras can do is help investigators piece together the details of plots after they are attempted, gather forensic evidence and identify suspects—all of which deepens their understanding of how terrorist networks operate.
