Re: If the accusation would have any merit
" Sad statistics prove that cases like this where the assailants can be identified tend to have a rather less happy outcome than a hangover and a bill that's higher than expected for the victim."
Sad statistics prove that around 3-5% of such accusations are demonstrably false / malicious, yet far too many men* faced with stories about rape immediately jump into "what if she's lying?" i.e. victim-blaming mode.
and yes, being gang-raped is "rather less happy outcome than a hangover and a bill that's higher than expected"
*I would say 'people' but it's predominantly men
