The main idea is how Brady material is extended to include impeachment evidence. Giglio v. United States holds that the obligation to disclose Brady material isn’t limited to exculpatory facts; it also covers statements or deals that could impeach a witness’s credibility, such as promises of leniency or cooperation in exchange for testimony. This ensures the defense can properly assess how trustworthy a witness is, which is essential for a fair trial. The other cases don’t address this specific disclosure duty: Miranda v. Arizona is about the right to counsel during interrogation, Brown v. Board deals with desegregation and equal protection, and Brady v. Maryland establishes the baseline requirement to disclose exculpatory evidence. So the case that addresses disclosure of Brady material besides Brady is Giglio v. United States.

The main idea is that Silver Alerts are about vulnerability, not just age. While many programs center on older adults, the alert can be issued for missing adults under 60 if they are considered at risk due to factors like cognitive impairment, disability, or other safety concerns. So an under-60 individual can qualify for a Silver Alert in places that use the vulnerability criteria, making the statement true. If a jurisdiction limited Silver Alerts strictly to those 60 and older, it would be false, but the policy this item reflects accepts the under-60 scenario when risk factors are present.

Baker Act receiving facilities are hospitals or institutions that have been designated by the state to accept individuals for involuntary examination under the Baker Act. These facilities must be able to provide immediate psychiatric evaluation and hold someone for up to 72 hours. North Shore Medical Center is not on the state's list of designated Baker Act receiving facilities, so it cannot serve as a Baker Act receiving facility. The other options are facilities that are designated to receive involuntary examinations, and thus can operate as Baker Act receiving facilities.

In this context, who controls the on-scene communications and can mute alerts is the supervisor. The supervisor has the delegated authority to manage the unit’s radio settings, including silencing the 10-33 tone, to maintain orderly communications, coordinate actions, and prevent unnecessary disruption during a situation. Higher-ranking officers, such as the captain, major, or the watch commander, oversee operations and provide direction, but the actual act of silencing the tone in the field comes from the supervisor who is responsible for the unit’s communications workflow.
