It seems impossible to stop the pendulum from swinging.
Allegations about Smith have been around for a very long time but no-one seemed to be bothered about them. That's the swing in one direction.
Then, everyone gets excited about dealing with sexual abuse and you get things like the recent Evans trial where some of the 'victims' testified that they did not believe any offence had taken place and did not know why they had been called to give evidence. And that'a the opposite swing.
It is very difficult for the police and the CPS to determine what are serious accusations and what are not but there is a clear need to do a better job.
