I take your point, but that is reliant on the numbers of guilty versus not guilty verdicts being less than is need for a majority verdict, and there is no guarantee that such cases would result in a hung jury.
This case was for TV, so there is an added pressure there to get the "right" verdict. In real life, how many jurors would be persuaded by the loudest voice in the room pointing out that they must acquit if there is doubt. It's difficult to argue with this point if each juror only has two options. A "not proven" gives a clear alternative.
Also retrials aren't guaranteed, and a range of additional factors (relative to the first trial) will be considered by the CPS before this decision is undertaken.
Criminals usually don't have qualms about lying when giving evidence. They can literally make up any lie that creates a reasonable doubt, resulting in an acquittal.
It's a slap in the face for victims, when they have gone through the ordeal of the crime, the ordeal of the police investigation, the ordeal or re-living the experience when giving evidence, the ordeal of being attacked by the defending barrister; only for a "not guilty" verdict to be given based (most probably) on fabricated "facts" and / or excluded evidence that was not put before the jury.
To see examples of how such victims are treated, just read the comments section of MailOnline, with ignorant people calling for victims to be tried for perjury etc.
