Duplicative

We determined that the maritime missions and responsibilities of the agencies are not duplicative and their efforts bolster the overall effectiveness of DHS maritime border security. Given the large area of responsibility, different activities, and limited resources, eliminating the maritime law enforcement responsibilities of either agency — or combining them — could be harmful to border security.  However, Air and Marine Operations and the Coast Guard could improve coordination in some areas.  DHS concurred with our two recommendations to improve oversight, and coordination of maritime operations.
