You've highlighted six instances over a 24 year period of life
I'm going by Bamber and others around him admissions.
You are not thinking it through!
I've highlighted 6 instances that show he had the experience and knowledge to understand a .22 is a low powered firearm and coupled with subsonic ammo is not going to create back spatter as evidenced by soc.
Why would you rely on JB? He went to prison at the age of 24 he is now still in prison at 64. Most of his sentence served as Cat A. I know you see him as some sort of Bear Grylls but I don't. His lengthy incarceration will have taken its toll.
Who are the others around him whose admissions you refer to. Afaik those around him pre-prison were not part of the farming/shooting community.
You are plagiarizing my posts by not thinking it through!
