Yes, I could add something here, because I've had some experience with this. It's very difficult to find out what's going on if you're stopped or queried. There are different regimes. Typically what happens is that if you want to question it, they might show it to a judge, but they won't show it to you and they won't show it to your lawyer, so the whole thing has an air of mystery to it.
There needs to be some way of correcting mistakes. Also, because of the way the records are kept, once something is there, it never disappears, but a comment may be added on. What happens is that once you're stopped, you're always stopped while somebody reads through everything and figures out what's going on.
The system, I would say, needs more accountability, more transparency, and there needs to be a possibility of completely eradicating a mistaken record.
