Describe the effect the photos had on the jury.

From the text:

Altogether, there were seventeen prints, and as they were passed from hand to hand, the jurors' expressions reflected the impact the pictures made: one man's cheeks reddened, as if he had been slapped, and a few, after the first distressing glance, obviously had no heart for the task; it was as though the photographs had pried open their mind's eye, and forced them to at last really see the true and pitiful thing that had happened to a neighbor and his wife and children. It amazed them, it made them angry, and several of them - the pharmacist, the manager of the bowling alley - stared at the defendants with total contempt.
