Easy: in success criterion 1.1.1 of WCAG 2.0:
"All non-text content that is presented to the user has a text 
alternative that serves the equivalent purpose, except for the 
situations listed below." 
Bogus alt does not meet this criterion.

Via "Understanding Success Criterion 1.1.1"
one can also find Failure F30: "Failure of Success Criterion 1.1.1 
and 1.2.1 due to using text alternatives that are not alternatives 
(e.g. filenames or placeholder text)"
<http://www.w3.org/TR/2008/WD-WCAG20-TECHS-20080430/F30.html>, which 
covers a very common type of bogus alt.

"Bogus alt" wouldn't constitute an "equivalent" according to WCAG 1.0.
