OT: Uh oh Henry Cavill may be in big trouble!

That's right--this is why we have a judicial system: because even multiple accusors and witnesses can be wrong (vide the Salem withchcraft trials; vide the McCarthy Communist hearings; vide American lynch law), and as you point out, no one is under surveillance 24/7--so we need an independent judicial body comprised (ideally) of an impartial judge and jury to weigh the claims and statements of those accusors and witnesses, to sift their accounts and determine the credibility and truthfulness of same. Of course, for you that's not fire-breathingly SJW enough, so you'd prefer to jettison all due process in favor of righteous popular vengeance--and I happily leave you to the sort of society you'll be facing if that ever completely obtains as the norm. It's already coming scarily close in some respects to becoming that sort of society as it is.
