I am finding several of the posts here that are critical of Sgt Nightingale very out of line with the information that is in the public domain. The main points I have gathered are:
He was given the gun and ammo in Afghanistan.
For reasons that don’t matter he left Afghanistan expecting to go back and so left a lot of his kit including the gun and ammo out there.
When he didn’t go back his kit was packed and forwarded to his UK address.
It was not unpacked at his address and while he was away from the address he had a serious medical event that affected his memory.
Then his address was searched in connection with another occupant. That search produced the unpacked gun and ammo.
If all of this is correct then it is clearly not a simple case of a bloke deliberately keeping a gun and ammo.
If any of this is not correct kindly put me straight.
