Witness one says the suspect wore a red hat. Witness two says it was a pink hat with a red band. The detail differs and because it does it feels right that both persons are probably eyewitnesses.
Different facts are emphasized in the 4 accounts at times, but that is different from direct conflict regarding the same facts that are discussed.
It’s important to focus on which facts are essential or necessary and which are not.
If two witnesses don’t present the same testimony on fringe elements (one witness reports red hat, 2nd witness omits the hat) but both assert the event occurred, we should consider the possibility that discrepancy regarding fringe elements are irrelevant. The accuracy—that the primary event actually occurred—is upheld.
