I'll let others determine my reputation. L&A tests can, if properly
conducted, help detect ballot programming errors. They are, however, of
very limited use in detecting the presence of malicious code, whether
emplaced by a crooked official, a hacker, or a crooked vendor. Since
voting machines usually know the current date and the scheduled date of
each election, a competent cheater will program them to cheat then but
to operate honestly on all other dates. Parallel testing (see, e.g.,
http://www-db.stanford.edu/pub/keller/2005/Shamos-rebuttal.pdf at s.3.3)
can help detect some such frauds, but it is difficult and time-consuming
to conduct properly, and any slip-up can permit malicious code to go
undetected.
