False accusations are extremely common, partly due to vulnerable people being brainwashed by cults and deluded mental health professionals.
Because of my connections to activists against quack therapies I know of many cases where completely innocent people end up in jail for terrible sex crimes of which they are completely innocent.
We live in a terrifying time in which mental health services have been infiltrated by criminals and very ruthless predators. Everyone is let down by this including victims of sexual crimes.
I think that people who claim they have been sexually assaulted or abused should have their phones examined, but it should be in a way that is undertaken by a specialist person who identifies relevant material to the police.
I went through a similar process myself when I was sexually assaulted and the defence lawyers wanted access to my medical records. I went through them with my GP practice manager who would have identified anything relevant to the police.
I did not like the process and experienced it as violating, however justice is the most important issue and given the level of false accusations, which is extremely high, we have to find ways to prove cases other then by simply personal testimonies of alleged victims.
The most important issues that need to be addressed IMO are
Police being trained by a variety of self described experts, many of whom are charlatans. Cops are gaining CDP credits for being trained to spot the signs of satanic ritual abuse by deluded quacks. This has lead to innocent people's lives being destroyed and predators evading justice. This has to stop
Mental health services not being fit for purpose and money being diverted into pseudo-therapeutic cults
Expert witnesses who are charlatans and frauds are a significant problem leading to all kinds of injustices
There is very little in the way of supportive services for survivors of sexual offences that has not been compromised by cults. This absolutely has to change. It is a terrible thing to guide vulnerable people who have been violated towards supportive services that will further violate them, all under the guise of "empowerment".
I don't have all the answers but just sharing my thoughts
