What allows a juvenile witness to write a statement?

The option indicating that a juvenile witness can write a statement by volunteering to do so reflects the understanding of consent and agency in legal settings. This is important because it acknowledges that juvenile witnesses must be willing participants in the process of providing information.

In many situations, particularly those involving minors, it is crucial to ensure that their contributions are made voluntarily to maintain the integrity of their statements and to protect their rights as participants in the legal system. This voluntary participation ensures that the juvenile witness is comfortable and understands the implications of their statements.

The other choices imply conditions that might not necessarily uphold the witness's autonomy. For instance, being instructed to write a statement might feel coercive, while being required by law could undermine the voluntary nature of the witness's contribution. Having a parent present might offer support, but it does not inherently grant the juvenile the autonomy needed to make the decision to write a statement independently.
