Final answer:
Bad evidence can factor into testimony by creating a false sense of certainty in a witness, leading to wrongful convictions. Suggestive police identification procedures can significantly influence witness testimony and subsequent trial outcomes.
Step-by-step explanation:
How might "bad evidence" factor into Jay's testimony in the murder of Hae Min Lee is a question that delves into the reliability of witness testimony and the impact of suggestive police procedures on a witness's confidence in their identification of a suspect. In criminal proceedings, this reliability can be crucial. As seen in the case of Jennifer Thompson and Ronald Cotton, where compelling testimony based on erroneous identification led to a wrongful conviction, the influence of suggestive police identification procedures can create a false sense of certainty in a witness.
These methods might include presenting lineups in a biased way to highlight the suspect, pressuring a witness to choose a particular person, or confirming their selection to reinforce their confidence. This is particularly problematic when it influences the outcome of serious criminal trials, such as murder cases, because it can lead to wrongful convictions and miscarriages of justice.
