Crime is down at the world's busiest passenger airport, and its "top cop" credits increased visibility of enforcement methods for much of the positive change. Specifically, Hartsfield-Jackson Atlanta International Airport (ATL) experienced about 12% less crime last year vs. 2013. Larceny, in particular, dropped 34%. Maj. Lane A. Hagin, commanding officer of the Atlanta Police Department Airport Precinct, attributes improvement in both areas to a more conspicuous policing presence throughout the facility.
