There are standards and ethics to hunting. Let's pick one: suppose you're the coward in the helicopter, and you shoot the pig in the leg, but think you killed it. The pig dies three days later, after a long, painful ordeal. (Hunters are expected to make a kill shot.) Many of these clowns in the helicopters are shooting pigs in any part of the body and leaving them to die painfully, in the hundreds. The other ethical issue is that hunting is mainly for the acquisition of food. Hardly any of those helicopter assholes will eat the pigs.
