The final argument is very weak. The decision of the jury seems more like wishful thinking. She should have use the HKD700000 as an leverage to prove that the defendant has bribed the witness. That should be a more plausible argument to convict him.
I think it was the last trial. You need to provide proof ASAP in the courtroom. She only admitted her debt in the bathroom, which doesn't count. You as a lawyer accepted her testimony to present to court if afterwards you say that your own witness credibility is tainted this witness won't be credible either way and will be nullified. The cops will have to dig that element for a next re-appeal should the jury let the accused go free. But yeah wishful thinking most rape cases are hard to prove unless a group of women come out and usually these guys its not their first time.
Is not really justice where the victim lost her life when he only be in confinement for the longest of 6 years and he is out again to live his life ....
