LiDAR (Light Detection And Ranging) is a camera that uses lasers. It can be mounted on an airplane and get detailed three dimensional images of everything below, even through dense tree canopy.
SWATTING is not most often calling in false terrorism threats. It is usually a tactic used to sic police on unsuspecting gun owners, especially those who carry. As paraphrased in the show, law enforcement is required to respond to all man-with-a-gun (MWAG) calls. The practice has resulted in numerous injuries and deaths. Being cooked up (just like the original series, if slightly less ham-handed) with a decidedly anti-gun messaging, it is hardly surprising that the show would doctor the meaning of the term.
