What type of evidence clearly shows some act or omission by the alleged violator?

The type of evidence that clearly shows some act or omission by the alleged violator is categorized as direct evidence. Direct evidence provides straightforward proof of a fact without the need for any inferencing or presumption. For instance, eyewitness testimony can serve as direct evidence if someone directly observes the violation occurring. Similarly, video footage capturing the act represents a clear demonstration of the behavior in question.

In contrast, circumstantial evidence requires a layer of reasoning to connect the evidence to a conclusion, meaning it might suggest that a violation occurred but does not definitively prove it on its own. Hearsay evidence involves secondhand reports of what someone else said, which is generally not admissible in court due to reliability concerns. Physical evidence, while tangible and important, refers to objects or materials involved and may not directly link to the person's action or negligence unless it is contextualized with other evidence. Thus, direct evidence stands out as the most concrete form of proof relating to an alleged violation.
