You observe a violent crime at a street corner, and it is about 8 pm. You are about 10 feet away from the incident. You feel you can describe the assailant (what he was wearing, his looks, male or female, what weapon he had) but you cannot clearly describe the person's looks. Would you be a good, reliable eyewitness? If you identify the assailant and testify, what could be an issue with the identification you have made?
