who votes not guilty in the preliminary ballot? what is his rational for doing so? how do the other jurors react?

All of the jurors vote “guilty,” except for the 8th Juror, who votes “not guilty.” The jurors react violently against this dissenting vote. Ultimately, they decide to go around the table, explaining why they believe the boy to be guilty, in hopes of convincing 8th Juror. When a discussion about the murder weapon, which was identified as the knife purchased by the defendant, a “one-of-a-kind” knife, begins, 8th Juror surprises the others by presenting an identical knife he had purchased in a pawn shop two blocks from where the boy lived a few nights prior, shattering the claim that the knife was so unique and identifiable.

i think that they are gulity because they are very naughty and they alaways lie to each other and they purchased the wrong thing,shattering the claim that the knifes was so unique and identifable.

All of the jurors vote gulity except for the 8th juror. When a disscussion about the murder the door opened and there was a weopon sticken out of the door where the boy lived a few nights priper,shattering again the claim that the knife has been found.
