Prisons are full of people convicted of historical sex offences, few of whom are rich and famous or part of any mainstream media background.
The reality is that it is often hard for people to process the fact that they have been raped, sexually assaulted or abused, let alone to find the strength to report it. Sex offending is rarely about sex and nearly always about power and control. They manipulate the narrative to shame victims into never speaking out, or not being believed when they do.
Twitter was a disgusting place over the weekend with posts about potential victims being money grabbing slags etc. And we have seen this time and time again, even on this forum.
I've no idea whether Russell Brand is guilty of any crime or not, and hope that these allegations are tested through the courts for all concerned. However, the miniscule rates of convictions for sexual offences is something we should all be ashamed of, and these media cases often makes this worse.
