So says Morgan Freeman's character Lucius Fox in 2008 in The Dark Knight[0].
The rest of the tech imagined in that scene is plausible today too, considering the density of WiFi/5G and research demonstrating the potential for its use as passive radar [1]. That paper metions a cooperative base station, but I am wondering if there is any value gained in knowing exactly what the traffic is (such as some of the intelligence community does) in modelling how the waves propagate and performing an even more passive observation.
