none of the museums 'allowed' anyone to test for cyanide residue except for a single official study by the Poles which was carried out to debunk, i believe, the Leuchter results (they failed) David being born a Jew had nothing to do with it, which is also obvious when you consider that Germar Rudolf, a German chemist who is not Jewish, also collected samples and had nothing to do with Cole - there was at least one other set of samples collected, but i forget by whom David, as far as i know, never physically collected any samples himself, nor did he hire anyone to do so - Zundel did though
