Its my belief that you as the parent have control over whether your child takes stand or not.
Jacksgal means well but this simply isn't true. Now it is true that the DA is unlikely to force her to take the stand. If he/she forces the victim to take the stand a well timed question like: "You didn't want to testify against so and so did you?" and "You are being forced to say the things you are saying, aren't you?" Will harm the case.
This is the very reason that many cases like this get such a light sentence. The victim does not want to testify or the parent doesn't want the victim to testify and the Defendant pleas to a much lighter sentence than they deserve.
While I totally understand your position, and I sympathize with you, think about this for a minute. How are you going to feel when this monster abuses another 10 year old girl? What if he kills her? People like this scum are not going to quit. He NEEDS to be put away for as long as possible. The Court will absolutely do BACK FLIPS to protect your child from any more stress than is absolutely necessary.
I will back up what another poster said. No defense attorney is going to question your daughter hard. It is somewhat likely they won't question her at all. A Judge is going to be down right aggressive with anyone who even makes your child nervous with their questioning on the stand.
It is even possible that the Judge will do the questioning in chambers with the attorney's present. I have seen where attorneys watch the judge question a child, then submit written follow-ups to the judge for the judge to ask. It won't be fun, but it won't be as bad as you might imagine.
I truly encourage you to have your daughter testify. This monster will do it again. Next time he may not leave the victim alive to testify. I know you don't want that on your conscience. I truly sympathize with your plight, good luck.
