What is the exact quote? - 'show me the man, i'll find you the crime.' (<-- not the exact quote)

‘Show me the man, I’ll find you the crime’

this is not an exact quote; this is instead the premise of a quote. i don’t know who said it or what the exact quote is, so my questions to you are: who said this quote, and what is the exact quote?

The meaning of the quote, inasmuch as I understand it, is that everyone has skeletons in his or her closet.
