They follow up with a rifle for the safety of the hunter! Even with a perfect shot an elephant can still have enough time to kill the hunter. Theyput a brain shot to instantly put the elephant down to decrease to danger.The shows that I have seen explain the process of elephant hunting.
Wrong! The first thing an elephant does when shot is turn and run. The videos your watching are white washing this "bowhunting" video with the danger factor to justify finishing it off with a rifle.
