Let’s say you’re in a crowded bar when somebody suddenly shoots at a patron. You clearly see a man carrying a firearm, but all hell breaks loose as you and everybody else scramble for the exits. In the terrifying seconds following the crime, you lose track of who discharged the firearm: it could have been 1 of 3 suspects. Afterward, the police interview you, but it is hopeless. Even bringing in the suspects for a lineup isn’t going to help you recall. There will be no “Perry Mason” moments, when the perpetrator breaks down under the weight of guilt and confesses to the crime. How can the authorities make an arrest?
