Judging only by actions, it would appear that these officials consider voter fraud to be a serious threat along the lines of smallpox – a highly contagious, lethal disease – and thus are willing to tolerate a high number of false positives in order to isolate and “cure” the true positives and protect the rest of the population from an epidemic. Opponents of these efforts can (and already have) suggested that such fears are overblown; in essence, that voter fraud is an isolated disease with a low degree of contagion.
