In the US, it's "innocent until proven guilty".
Media is so quick to assume the person is guilty just because of an allegation.
I don't think this is in practice true, as a matter of fact rather than an ideal. People don't, in general, behave the same with other people who are currently being prosecuted for a crime.
This certainly doesn't mean (most) people support vigilantism or witch hunts, or even that you assume guilt. However it seems clear the vast majority of people are fine with the idea that you might be "careful" with someone who is suspected of a crime, especially one being actively prosecuted. To the degree that many will claim they have a right to know this is happening, i.e. they will argue that news should be carried on this (although perhaps no editorializing). This absolutely is not the same as presumption of innocence.
Sometimes this is very unfair, obviously. But "the social contract" as it is practised seems to be pretty ok with that.
