If being exposed to the "wrong" people for a few hours is all it takes to make the voting machines unsafe, isn't that an admission that they weren't remotely safe to begin with? I argue this holds for any black box that requires an army of computer experts and electron microscopes to truly verify... and that verification only lasts until the next time the wrong person is in the same room as the black box.
