Witnesses testify from the witness stand adjacent to the judge's bench, facing the jury and attorneys. Before testifying, each witness takes an oath or affirmation to tell the truth. On direct examination, the calling attorney asks open-ended questions to elicit the witness's narrative. On cross-examination, opposing counsel may use leading questions to challenge credibility, expose bias, or highlight inconsistencies. The judge may exclude witnesses from the courtroom under the Rule of Sequestration (Rule 615) to prevent them from tailoring testimony based on others' statements.
Attorney: "Please state your name and tell the jury what you observed on the evening of January 12th."
Attorney: "Isn't it true that you were over 100 feet away and it was dark when you claim to have seen the defendant?"
Judge: "The witness may step down. Thank you for your testimony."
Students frequently confuse the scope of lay witness testimony. Under FRE 701, lay witnesses cannot offer opinions unless rationally based on their perception and helpful to the jury, such as estimating speed or identifying a voice.

Davis v. Alaska, 415 U.S. 308 (1974)
Held that the Confrontation Clause prevails over a state's interest in protecting juvenile records, guaranteeing the right to cross-examine about bias.
