Lemmons testified that he compiled the list of sexually
explicit sites that should have been blocked by entering the
terms "free adult sex, anal sex, oral sex, fisting lesbians, gay
sex, interracial sex, big tits, blow job, shaved pussy, and
bondage" into the Google search engine and then "surfing" through
links from pages generated by the list of sites that the search
engine returned. Using this method, he compiled a list of 197
sites that he determined should be blocked according to the
filtering programs' category definitions. Lemmons also attempted
to compile a list of "sensitive" Web sites that, although they
should not have been blocked according to the filtering programs'
category definitions, might have been mistakenly blocked. In
order to do this, he used the same method of entering terms into
the Google search engine and surfing through the results. He
used the following terms to compile this list: "breast feeding,
bondages, fetishes, ebony, gay issues, women's health, lesbian,
homosexual, vagina, vaginal dryness, pain, anal cancer, teen
issues, safe sex, penis, pregnant, interracial, sex education,
penis enlargement, breast enlargement, . . . and shave."
If separate patrons attempted to reach the same Web
site, or one or more patrons attempted to access more than one
page on a single Web site, Finnell counted these attempts as a
single block. For example, the total number of blocked requests
for Web pages at Tacoma Library during the logged period was
2,812, but Finnell counted this as only 895 blocks of unique Web
sites. Of the 895 unique blocked sites, Finnell was unable to
access 59, yielding 836 unique blocked sites for his team to
review.
The confidence intervals that Finnell calculated
represent the range of percentages within which we can be 95%
