Re: arrested for not testifying?
But you need to say that to the court so it is on record that you don't remember. It's because it's a criminal case, not a civil one like sueing someone, they have to carry it through all the way. If you dont turn up or don't testify you will be seen as perverting the course of justice, even if all you are going to say is "I don't remember."
I agree it is a bit silly that they are going to all this hassle even though you don't remember, but the fact that they caught someone, which I suppose doesn't happen all too often with a mugging, it needs to be carried through and they have to dot their i's and cross their t's.
