Little doubt he killed her intentionally; the prosecution couldn’t prove it.
The sentence is lenient, but her family were happily taking money from Pistorious after the killing.
Working in transport myself, I agree with your sentiments. My cousin’s husband avoided a prison sentence by the skin of his teeth after a collision in his HGV because he “opted” to plead guilty to death by careless driving. He was told he would get 5 years if found guilty of death by dangerous driving.
Stinks doesn’t it?
