This rule follows from certain axioms in this system and from the manner in which a conditional probability is defined. The process of conditioning allows us revise a probability in light of new evidence. Bayes's rule concerns calculation of the probability of hypotheses we are considering, given or conditional upon new evidence. Thomas Bayes, a Unitarian clergyman in England, is usually given credit for first seeing the essentials of this rule. In an epistemic sense Bayes's rule shows us how to revise our probabilistic beliefs about the likeliness of hypotheses, on the basis of new evidence we obtain.
However, this distinction does matter to us, since a major concern in our analysis is the specific case made by the prosecution at trial and unsuccessfully countered by the defense. Again the prosecution alleged specifically that Sacco had shot and killed Berardelli. As the title of his 1986 book indicates, Russell does not hedge probabilistically in his belief that H2 is the true hypothesis. He regarded the Gambera evidence as being conclusive on H2 (1986, 13). In addition Russell viewed as conclusive certain ballistics tests, performed in 1983, showing that the bullet that allegedly killed Berardelli came from the 32-caliber Colt that was taken from Sacco at the time of his arrest (1986, 160-162).
As we noted, either Sacco or Vanzetti could have been put to death for (1) shooting Parmenter and/or Berardelli while in the act of robbing them of the payroll they were carrying, or (2) for being an accomplice to the robbery and shooting. We will say that involvement in the South Braintree crime means either ( 1 ) or (2). There are four hypotheses or possibilities that might be entertained regarding the involvement of Sacco and/or Vanzetti in the crime: H,: H2: H3: H4: Both Sacco and Vanzetti were involved in the crime.
