Eloquently said, as usual. But although every notion you said it 100 percent true, you still cannot rush to judge someone. Just imagine if someone made up allegations about you or someone in your family. Would you still say that it is imperative to send a strong message immediately without having the facts fully explored?
Again, this is a terribly sad situation any way you slice it. But we must follow Daas Torah and halacha when it comes to lashon harah, and we cannot make justifications ourselves, even if they make so much sense.
You're right, of course, there can not be a rush to judgement. More than 20 cases is not rushed.
I'm not in favor of mob justice, or the likes of public walls of shame. Sure, most listed are guilty as sin. But there are a few famous cases of false accusations. Almost always, the false ones have a single accuser, and the real cases will end up with multiple victims speaking up after the initial one takes the plunge.
Of course, there is a danger of swinging too far into the "believe all women/victims" side, but it would be nice if the default communal attitude was to bend over backwards to find ways to be sensitive to victims in the way it does now for the accused.
