What can be a key factor in establishing an effective alibi?

A key factor in establishing an effective alibi is physical evidence supporting the alibi. Physical evidence can include items such as surveillance video, GPS data, transaction receipts, or eyewitness accounts that corroborate the person's whereabouts at the time of the alleged crime. This type of evidence not only supports the person's claim of being in another location but also provides tangible proof that can be critically analyzed and presented during legal proceedings.

The strength of an alibi often hinges on its ability to be substantiated by concrete evidence, as this reduces speculation and increases credibility. In a court of law, juries tend to favor verifiable facts over testimonies that cannot be backed by physical proof. An alibi supported by strong physical evidence can create doubt in the minds of jurors regarding the alibi's validity, which is essential for a defense strategy.
