res ipsa loquitur (Latin for "the thing speaks for itself"

有s，但是我放到地方不對。

Let the facts speak for themselves or the thing speaks for itself. 

I started with "let the facts speak for itself", then thought "itself" is singular, so I changed it to "let the fact speaks for itself".   I should have said "Let the facts speak for themselves".
