Which type of evidence is used to support claims in a courtroom?

Eyewitness testimony is a critical form of evidence in a courtroom because it provides firsthand accounts of events as they occurred. This type of evidence can establish facts relevant to the case, such as who was present at the scene of a crime, what actions were observed, and the context surrounding those actions. Eyewitnesses are typically called to testify, and their credibility can significantly influence a jury's perceptions and conclusions.

In contrast, personal opinions, while they may reflect an individual's feelings or perceptions, do not carry the same weight as factual evidence in court. Social media posts can be relevant in some cases but often lack reliability due to potential biases and the inability to verify the authenticity of the information. Assumptions, by their nature, are not based on direct evidence or observation and do not provide a factual foundation for supporting claims in legal proceedings. Thus, eyewitness testimony stands out as a tangible and robust form of evidence essential for building a case in court.
