It is a fact that he was killed with a bullet from an assault rifle.
It is a fact that assault rifles from F&F were found on site where he was killed, used by those that killed him.
The bullet was too badly damaged to confirm which weapon it came from. I know it is hard for lemmings to connect the dots as you are used to your masters drawing the pictures for you.
Thank you, so there is no proof, just speculation. I may be a lemming, but facts are facts and connecting the dots is connecting the dots.
I hope you are never tried on just connecting the dots, the dots can sometimes be wrong.
