I'll try to explain the Argument from Ignorance clearer with an example:
It's up to the DA to provide evidence against a suspect - a DA can't just say "it's reasonable to assume the suspect is guilty because there's no evidence to clear him."
The absence of evidence against an idea is not evidence for an idea.

Here's a link to the Wikipedia entry on this logical fallacy:
"[Argument from ignorance] asserts that a proposition is true because it has not yet been proven false (or vice versa)...In debates, appeals to ignorance are sometimes used to shift the burden of proof."
Like in my example above, the DA attempted to shift the burden of proof to the plaintiff. In this case the burden of proof is on Bigfoot believers specifically because Bigfoot doubters can't search every square inch of the globe to prove Bigfoot doesn't exist. It's logically not possible to prove Bigfoot doesn't exist - but that doesn't mean he does. In a nutshell that's it.
