Defendants have a presumption of innocence, but accusers do not have a burden of mathematical proof. The closest you get to "innocent until proven guilty" in US law is common law's Ei incumbit probatio qui dicit, and the Latin word "probatio" does a lot more work than just "mathematical proof".
There's a good 30 minute Google jag you can have about this if you go search for [legal standards of proof].
