What type of evidence is obtained from witnessing an individual set a fire?

The type of evidence obtained from witnessing an individual set a fire is classified as direct evidence. Direct evidence refers to information that directly links an individual to a crime or act, without the need for inference or presumption. In this case, being a witness to the act of setting the fire provides firsthand, observable evidence of the person's involvement in the action.

Direct evidence is considered the most compelling form of evidence because it comes from a source that has directly observed the event. Testimonial evidence, while also important, would typically involve someone describing what they saw rather than the firsthand observation itself. Circumstantial evidence, on the other hand, relies on the connection of various facts and circumstances that suggest a conclusion, rather than providing direct proof. Physical evidence involves tangible objects that can be presented in court, but witnessing an act does not fall under this category, as it pertains to the observation rather than the physical remnants of the act.
