I'm not skilled in the way of understanding legal jargon with respect to the terms "evidence" and "proof". They likely mean something other than what you imagined, or at least, how they work to either exonerate or convict someone of a crime. Seth Abramson does a great job of breaking them down in a thread on Twitter. He talks about what it takes to indict someone and what is needed to gain a conviction. The thread is 50 tweets in total so be sure to expand the link so it shows all 50 tweets. Try to avoid being distracted by other tweets that may show up in response—just follow Seth's. Here's the link:
