In the US, it's "innocent until proven guilty".
Media is so quick to assume the person is guilty just because of an allegation.
The question is where do you draw the line as an individual.
That's all it means. Obviously judges are not supposed to come into a case assuming you are guilty, but you can say that about any type of case. The phrase certainly doesn't mean we have to pretend that you are perfectly innocent up until the point of verdict.
