Would small glass fragments be considered class evidence or individual evidence that can be uniquely associated with a broken bottle?

Small glass fragments are generally considered class evidence because they can be associated with a specific type or brand of bottle based on their physical characteristics, such as color, thickness, and refractive index. However, if the fragments are large enough and exhibit unique features, such as specific patterns of fracture or markings that match precisely with a broken bottle, they could be considered individual evidence. In forensic analysis, the context and the ability to match fragments to a specific source play a crucial role in determining their evidential value.
