Why aren't the photographers who shoot wild animals attacked?

There must be cases of being attacked by wild animals, but photographers will have corresponding methods.

The National Geographic Channel has a program to shoot tigers in the Mangrove Zone in Zundel. The photographer hid in a tent in a tree to shoot. Local tigers have a "tradition" of eating people, which means they are not afraid of people at all. The photographer took a revolver with him. Pistol bullets have no warheads, empty bullets. He said that if a tiger approached at night, the loud noise and fire of the gunfire were enough to scare the tiger away.

Remember a British couple who went to Africa to make a crocodile documentary. They made a crystal transparent coffin and put it in the water. People hid in coffins equipped with equipment to shoot crocodiles. To avoid being attacked. Besides these methods, there are many shooting methods that can reduce the possibility of being attacked by photographers. Some people install cameras on elephants' noses. There is a camera on the remote control car, and the body is disguised as a stone. These methods can be used to photograph close to wild animals. Even take close-ups
