  Recent papers by Busza et al. and Dar et al. have considered empirical bounds
on the risk of producing a hypothetical stable negatively charged strangelet at
the Brookhaven relativistic heavy ion collider (RHIC) experiments, and thereby
destroying the Earth. We examine here ways in which these bounds could,
hypothetically, be evaded. We find several,some of which have not previously
been considered. These possible flaws do not affect the theoretical arguments
against the existence of negatively charged strangelets or the possibility of
producing them at RHIC if they were to exist.
