 Small Town Murder: A person accused of murder in a small town was seen driving to the small town at a time prior to the murder. The prosecution’s theory is that he was driving there to commit the murder. The defense theory is an alibi: he was driving to the town to visit his mother. The probability of this evidence if he is guilty equals that if he is innocent, and thus the likelihood ratio is 1 … Yet, every judge in every trial courtroom of the country would admit it [as relevant evidence]. (The difficulty has been formulated by Ronald Allen, see the discussion in Park et al. 2010)
