Polar Throne

I was excited to watch this but the opening scenes where the guy shoots himself in the head as well as other disturbing images. I don’t understand why this was in this documentary? I wanted to show this documentary to my 18 year old daughter and I was trying to fast forward through all the disturbing images when it landed right on the shooting suicide and she cried. It scared her. This has been out for awhile why has this not been edited? It says rated 16 with violence and foul language but this was beyond that.
