The best way to check an alibi is by

• A. By memory recall
• B. By actual investigative methods
• C. By cross-examination only
• D. By asking the subject to confirm times

Answer: (B)

Alibi verification hinges on gathering objective, verifiable evidence through real investigative methods, not just relying on memory or how someone answers questions. To confirm where someone was at a specific time, investigators search for independent proof that can be checked by others. This includes reviewing surveillance footage from the relevant period, examining access or entry logs, looking at transaction records and receipts, and checking phone, GPS, or transit data. Eyewitness accounts who can corroborate the timeline, and any other records like hotel bookings, work schedules, or public records, all help build a solid, independent timeline. When these pieces align, the alibi stands up to scrutiny; when they don’t, the alibi is challenged.

Relying on memory alone can be unreliable because memories fade or become biased over time. Cross-examining someone can reveal inconsistencies, but it doesn’t provide independent verification of where they were. Simply asking someone to confirm times depends on their recall and honesty, which can be subjective. The strongest alibi is one that can be corroborated by external, verifiable evidence gathered through proper investigative methods.
