"Innocent until proven guilty" is a good way to run a court or arbitration service, but a lousy way to live. I know that sounds harsh.
People are either guilty or they aren't. Your decision (or court verdict or even evidence) doesn't change their guilt or innocence. You might be wrong either way.
But, I give people the benefit of the doubt. Unless I know from first hand experience that they either did what they are accused or, or are likely to have done it based on a history I have personal knowledge of.
"Innocent until proven guilty" is being nice, but it can also be foolish and suicidal. Instead, I'll give even the "proved" guilty the benefit of the doubt, while never going to condition white, no matter who it is. If, from personal experience, I know they are guilty and dangerous, though, all bets are off.
