I'm sorry, maybe I wasn't clear - my question was on R' Eli Turkel's
unwritten premise that BD _does_ accept evidence aside from Shnaim Eidim. I
was asking if this was indeed the case. IIRC, we had a thread a while back
about the permissibility of using DNA to matter an Agunah (for example,
after 9/11), but that is a whole different set of rules.
