Final answer:
The investigative approach including testimonial evidence, documentary evidence, physical evidence, and personal observations is referred to as the Investigation square. It is crucial in law and criminal justice to select verifiable evidence that meets legal standards. Eyewitness testimony, though commonly used, can be unreliable, emphasizing the need for thorough evidence gathering.
Step-by-step explanation:
An investigative approach that includes testimonial evidence, documentary evidence, physical evidence, and personal observations is referred to as the Investigation square. This approach is integral to various fields but is particularly relevant to law and criminal justice. It is critical to choose the right types of evidence to support a case, ensuring that each piece of evidence is rooted in verifiable facts and meets the rigorous standards of the legal system.
For instance, the Personal Data Notification & Protection Act of 2017 provides a definition of a security breach that helps in understanding the kind of documentary evidence that may be relevant in cases involving cybercrime. Similarly, understanding the development of historical evidence can be crucial in legal contexts that deal with longstanding issues.
Courts often rely on eyewitness identification and testimony to prosecute criminals, making it a common form of testimonial evidence. However, as knowledge advances, it is understood that eyewitness accounts can be faulty, sometimes leading to wrongful convictions.
The process of gathering evidence requires thoroughness, whether it involves re-watching a film several times for a review, observing an employee for performance evaluation, or re-reading a written argument to highlight key points. It's always prudent to gather more evidence than might seem necessary at first to ensure the most compelling and relevant information supports the case.
