I try to avoid using anecdotes in situations such as this, as it's really not relevant, but I want to counteract some of the anecdotes being used in this thread.
Firstly, I have never known someone lose their job after being accused of a crime. Suspended on full pay yes, never sacked - unless found guilty.
Secondly, in my experience, when a man is accused of a sex crime, people tend to either not know anything about it until a court verdict (unless a high profile case) or people side with the accused on the basis that women lie and nobody likes to think that a "normal" person would do that, because of course all rapists and abusers are weirdo, bogeymen in dark alleys aren't they 
I recall one case where the accused only line of defence was that he couldn't remember the details, no denial. The community mocked and bullied the accuser and not the accused, his fiancé went on to marry him, no questions asked.
I'm sure some lives are ruined by false allegations, but many more are ruined by a justice system which stacks everything against them.
FWIW, some people have been lobbying for this change in the law for years, is anyone really naive enough to think this isn't being proposed to protect powerful men in government. Come on!
