Rain Dog, I am a little perplexed by your comment that

"his motorcycle collided head-on with a vehicle driven by Sacoolas that was on the wrong side of the road outside a US military based in Northamptonshire in August 2019."

Surely if she was on the wrong side of the road, as you suggest, she collided with him.

I realise this may seem pedantic, but in a court of Law blame, or guilt, is decided on our choice of words.
