now this; Reducing Witness Error: Eyewitness Identification Policy Reforms Although we highlighted earlier in this chapter a number of factors that may undermine the reliability of eyewitness evidence, this does not mean that all eyewitness evidence is necessarily poor. Eyewitnesses may provide highly reliable evidence, even though their recollections can become contaminated and otherwise influenced (Wixted et al., 2018). How might we ensure, then, that eyewitness evidence is as reliable as possible? As discussed in the previous section, the law provides some basic protections for suspects from mistaken eyewitness identifications, but these protections are far from foolproof. Experts have developed a set of recommended changes to police practices that may help reduce mistaken identifications and increase the overall reliability of eyewitness evidence. Many of these recommendations have been incorporated into legislative guidelines, as illustrated in the Connecticut statute reproduced above, or in analogous administrative regulations. A recent scientific review, or "white paper," on the topic offered nine specific recommendations related to system variables (Wells et al., 2020), some of which are discussed below
