Sometimes CPS would push a case forward without much of a case because pressure was put on them by the complainants family, for example.
Cant speak for the past but that is such bollox in the modern day life of a victim - they aren't allowed to speak to the CPS as a matter of course, and any pressure they put on the CPS - as you say - is handed over to the defence who then twist that.
As for the law does its course, I am quite, quite sure that you wouldn't trust your children and your family and their friends with a lot of these "innocent" men, and even if you did, you would be in a better place than the children whose innocence you were risking, because you would know who and what you were chosing to let into their lives.
The defence can introduce anything they like, factual or not, they can make up what they like - so long as the defence barrister does no "know" it is a falsehood, there is no burden of evidence on the defence in the same way as there is for the prosecution, it is the defence job to introduce reasonable doubt, even if that reasonable doubt is entirely based on a pack of lies that cannot be backed up or evidenced.
In addition an awful lot of evidence is suppressed, because the accused has a lot more rights than the victim, what jury wouldn't feel sick if they knew the man they had just let walk free had over 100 arrests for DV on the woman he has just painted as a complete slapper, but this is not allowed before a jury because there have never been any convictions.
I have stood in court and seen men and boys, who are well known in their local communities for high violence, disruption, anti social behaviour, painted as saints, while their victims, who have never put a foot wrong, are vilified in court, sometimes along with their families, regardless of whether their families play a part inthe trial and have a chance to defence themselves.
In our case, the fact I was a hysterical sobbing wreck unable to enter the court room for the summing up, was used to paint me as an uncaring person who - and I quote "couldn't be bothered to be there", of course, as the defence barrister gets the last word, that was the last thing the jury heard.
Also I have seen jurors ASLEEP, I mean seriously asleep, during trials, more than once - how can they sleep and be allowed to sleep and then have a clear picture of what has happened.
It is well known and well accepted in CJS circles that conviction rates are too low and many, many guilty men are walking around out there and that juries do not like to jail young white "respectable men" in case they get it wrong.
Also, I keep reading about women and girls, men and boys also get abused and raped, and some charities consider that under reporting is 10 times that of female under reporting - which of itself is shockingly low.
The law is an arse that fails on all levels, if there were more successful prosecutions, if less guilty men walked free, it would be better for - because not guilty would mean exactly that.
Bitter personal experience tells me - that even where there has not been an aquittal it is the victim and their family who have their lives destroyed, and I have heard that hundreds of times.
After what I have seen and heard and been through, I can seriously say, I would never ever subject any member of family that is the farce of a criminal justice system in this country for a victim, and that - saddens me more than anything, it was worse than the abuse in the first place.
