My Opinion: If all the interviews are as boring as these, I'm ready for the other kinds of evidence of what President Trump did wrong such that he deserves to be impeached. Let me see. I've read that there are different kinds of evidence that are examined in the search for truth. I'm ready to hear the demonstrative, digital, direct, documentary, exculpatory, forensic, or physical types of evidence that President Trump committed an impeachable offense. Bring on the evidence list.  Truth demands it. https://i-sight.com/resources/15-types-of-evidence-and-how-to-use-them-in-investigation/ Demonstrative Evidence An object or document is considered to be demonstrative evidence when it directly demonstrates a fact. It’s a common and reliable kind of evidence. Examples of this kind of evidence are photographs, video and audio recordings, charts, etc. In a workplace investigation, this could be an audio recording of someone’s harassing behavior or a photograph of offensive graffiti. Digital Evidence Digital evidence can be any sort of digital file from an electronic source. This includes email, text messages, instant messages, files and documents extracted from hard drives, electronic financial transactions, audio files, video files. Digital evidence can be found on any server or device that stores data, including some lesser-known sources such as home video game consoles, GPS sport watches and internet-enabled devices used in home automation. Digital evidence is often found through internet searches using open source intelligence (OSINT). Challenges of digital evidence Collecting digital evidence requires a skillset not always needed for physical evidence. There are many methods for extracting digital evidence from different devices and these methods, as well as the devices on which evidence is stored, change rapidly.  Investigators need to either develope specific technical expertise or rely on experts to do the extraction for them. Preserving digital evidence is also challenging because, unlike physical evidence, it can be altered or deleted remotely. Investigators need to be able to authenticate the evidence, and also provide documentation to prove its integrity. 7. Direct Evidence The most powerful type of evidence, direct evidence requires no inference. The evidence alone is the proof. This could be the testimony of a witness who saw first-hand an incident of sexual harassment in the workplace. 8. Documentary Evidence Most commonly considered to be written forms of proof, such as letters or wills, documentary evidence can also include other types of media, such as images, video or audio recordings, etc. 9. Exculpatory Evidence This type of evidence can exonerate a defendant in a – usually criminal – case. Prosecutors and police are required to disclose to the defendant any exculpatory evidence they find or risk having the case dismissed. 10. Forensic Evidence Forensic Evidence is scientific evidence, such as DNA, trace evidence, fingerprints or ballistics reports, and can provide proof to establish a person’s guilt or innocence. Forensic evidence is generally considered to be strong and reliable evidence and alongside helping to convict criminals, its role in exonerating the innocent has been well documented. The term “forensic” means “for the courts”. Its use in workplace investigations is generally limited to serious cases that may end up in court. [I've heard enough of this type:] 11. Hearsay Evidence Hearsay evidence consists of statements made by witnesses who are not present. While hearsay evidence is not admissible in court, it can be relevant and valuable in a workplace investigation where the burden of proof is less robust than in court. 12. Physical Evidence As would be expected, evidence that is in the form of a tangible object, such as a firearm, fingerprints, rope purportedly used to strangle someone, or tire casts from a crime scene, is considered to be physical evidence. Physical evidence is also known as “real” or “material” evidence. It can be presented in court as an exhibit of a physical object, captured in still or moving images, described in text, audio or video or referred to in documents. 13. Prima Facie Evidence Meaning “on its first appearance” this is evidence presented before a trial that is enough to prove something until it is successfully disproved or rebutted at trial. This is also called “presumptive evidence”. 14. Statistical Evidence Evidence that uses numbers (or statistics) to support a position is called statistical evidence. This type of evidence is based on research or polls. 15. Testimonial Evidence One of the most common forms of evidence, this is either spoken or written evidence given by a witness under oath. It can be gathered in court, at a deposition or through an affidavit.
