Some writer I forgot who checked the very scale O'Conner used and said it was out of calibration by 1-2 grains high. No idea if it was like that when he used it but I wouldn't doubt it. Someone else said he would put black tape over the digital clocks to avoid having to set them. He wasn't a tech-y.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
