There’s not much these days that can shock the sensibilities of ordinary human beings, but this story might be one of those exceptions.

FBI Director Kash Patel went swimming on a “VIP Snorkel” trip near the remains of the USS Arizona, in which nearly 1,000 American sailors and Marines have been entombed since December 7, 1941. Some people may say it’s no big deal but others are shocked by his lack of discretion and decency.

The New York Times reported:

Last summer, the F.B.I. director, Kash Patel, capped a whirlwind South Pacific trip with a snorkel trip in Hawaii.

There, Navy SEALs used two boats to transport and escort Mr. Patel and nine other people on what a Defense Department email called a “V.I.P. Snorkel” next to one of the military’s most sacred sites, the underwater tomb of the U.S.S. Arizona that holds the remains of more than 900 Navy sailors and Marines who died at Pearl Harbor.

Mr. Patel swam in the vicinity of the tomb for 30 minutes, according to the Navy.

Out of respect for the dead entombed in the wreck of the Arizona, rules bar visitors even from wearing swimwear at the memorial. With some exceptions over the years for dignitaries, the only people allowed in the water around the tomb are military and National Park Service divers interring the remains of the last Arizona survivors in the wreck, or conducting annual maintenance surveys, according to a former Navy officer and a former National Park Service official familiar with restrictions at the site.

Officials from the Navy and the Defense Department said V.I.P. “tours” near the Arizona were common, but they declined to say how often they take people snorkeling. A Navy spokeswoman declined to identify the nine people who joined Mr. Patel on the trip. The F.B.I. said that Adm. Samuel J. Paparo Jr., the head of the United States Indo-Pacific Command, invited Mr. Patel to Pearl Harbor.

The New York Times obtained details of the Pearl Harbor trip through a Freedom of Information Act request and information from a former F.B.I. official. Mr. Patel’s participation in the snorkeling trip was reported earlier by The Associated Press.

The idea of a high-ranking government official receiving an escort from the SEALs for a recreational swim near the tomb is “horrifying,” said William M. McBride, a Navy veteran and professor emeritus of history at the U.S. Naval Academy in Annapolis.

“This is a war grave with the same legal status as Arlington National Cemetery,” Mr. McBride said in an interview. “Snorkeling around Arizona is as disrespectful as playing kickball on top of the graves at Arlington.”

The Pearl Harbor trip was at the end of an itinerary in which Mr. Patel visited F.B.I. facilities in Hawaii, Australia and New Zealand. Disclosure of the snorkeling tour, and new details about other trips he has taken, comes as Mr. Patel is already under scrutiny for blending leisure travel with official business or instructing F.B.I. employees to make accommodations for him and his girlfriend, Alexis Wilkins.
