This may not work in ATL depending on whether your flight arrives at E or F. If you arrive at E the passengers are split depending on whether you're connecting or ATL is your final destination. If you arrive in E and are connecting you go through customs and clear security in E, however if you arrive in E and ATL is your final destination you go through customs in Terminal F which allows you to leave the airport without needing to clear security. If you arrive you E and are connecting there is no way to leave the airport after customs but before the TSA checkpoint.
