Cross-examination is a legal process where a lawyer questions a witness who has already provided testimony in a court case. This questioning occurs after the witness has been examined by the opposing lawyer, allowing the cross-examining lawyer to challenge the witness's statements, credibility, and reliability. The goal is to uncover inconsistencies or biases that may affect the case's outcome. During cross-examination, the lawyer often asks leading questions, which suggest their own answer, to control the narrative. This technique is crucial in trials, as it helps the jury or judge assess the truthfulness of the witness's testimony and the overall strength of the evidence presented.
