What is true about a witness regarding the facts in issue?

The statement regarding a witness that is true is that a witness does not necessarily know all the facts in issue. In a legal context, a witness is typically someone who has observed an event or has information about it, but their knowledge is limited to what they personally experienced or are aware of. Witnesses provide evidence based on their specific observations, which may not encompass all elements of the case or situation being evaluated.

It's important to recognize that while witnesses can contribute valuable perspectives, they may not have complete knowledge of the broader context or all facts relevant to a particular issue. Their testimony is valuable but inherently limited to their direct experiences or expertise.
