Barack Obama visited Australia during his presidency and the Secret Service had to clear a river that was adjacent to a reception building. The thing is that river was infested with crocodiles but that didn't even slow them down. Using scuba gear they just suited up and dove in. They didn't ask for help or advice... They locals just watched on in horror.
Thankfully all went well but they are some brave SOBs.
... And apparently they don't have a sense of humour.
