In informal preliminary discussions the prosecution and the defense had come to an agreement not to bring up the subject of radicalism during the trial. Katzmann had also offered to agree “that no particular bullet came from any particular gun” and refrain with the defense from trying to prove one way or the other whether the murder bullets had been fired from Sacco’s automatic or Vanzetti’s revolver. Moore had refused, exclaiming melodramatically that he was being asked to turn his sword into a shield, and insisting on being free to have the bullets and guns examined by experts. Officially Moore, assisted by William Callahan—the lawyer engaged for Sacco and Vanzetti in the Brockton police court—represented Sacco, and officially the McAnarney brothers represented Vanzetti, but this was merely a maneuver to give both Jerry McAnarney and Moore the right to argue before the jury and to cross-examine. In reality Moore was as completely in charge as if he had been captain of a ship. The contention of the Commonwealth, Assistant District Attorney Williams said in his explanatory statement, _is that this crime was committed by five men; that use was made of this stolen Buick car which after its theft from Dr. Murphy of Natick had been kept in the curtained shed of the Coacci house in West Bridgewater; that on the morning of the murder it was taken from the Coacci house and was driven to South Braintree; that they picked up Vanzetti at the East Braintree station; that the men who guided and drove that car were very familiar with the localities of West Bridgewater and the roads leading to and from that section; that they went down to the railroad crossing after the shooting, and made that hairpin turn to throw their pursuers off the scent ... that they proceeded by those back roads, Oak Street and Chestnut Street, until they got to the old turnpike, which, though a rough road, furnished a direct means of access to the West Bridgewater locality; and they tore down there and either started to take Vanzetti over to Plymouth and for that reason went over the Matfield crossing or went over there with the idea of perhaps disposing of something in the Matfield River ... found it inadvisable to do that which they intended to do, came back over the Matfield crossing and subsequently abandoned their car in the region adjacent to the Coacci house._ Williams claimed he would later show that Mike Boda was seen driving a Buick touring car during the winter of 1920. Reminding the Jurymen of Puffer’s Place, the house they had seen the day before, he gave an unsubstantiated account of the police visiting the shed and finding traces of a hole recently dug in the dirt floor as well as tire marks to the left of the boards on which Boda had kept his Overland.
