 When multiple items of evidence depend on one another—as may happen in many legal cases—this situation is modeled by the evidence dependency idiom. Following an example by Fenton and Neil (2013 [2018]), if one of two security cameras directed at the same location captured an image of someone who looks like the defendant but isn’t him, it is likely that the same person walked by the second camera, which also captured the same image. In such cases, presenting the second recording as independent from the first would lead to overestimating the strength of the evidence.
