Only seeing this now, and hope you are a bit better already! It surely brings back memories, of my big accident in '84, altered my life forever, but still riding!
That whole saga stinks to me,you must have a claim/case for incompetance or corruption in police/cps surely?
I wonder if some outside pressure or favouritism/influence is involved? I got shot in the leg some years ago and encountered nothing but obstruction trying to get the known culprit prosecuted.
