Someone making a false accusation is using the system designed to protect people and offer justice (the legal system), as a weapon.

This should carry extremely harsh penalties. I would say 20 years per false accusation, and certainly far stricter sentencing than rape itself.

Attacking/killing a police officer is considered an even more serious crime than conventional assault/murder. Not because a policeman's life is worth more or less than any other innocent person, but because in addition to the regular crime it's an attack on society.

False rape accusations are the same. They subject innocent men to horrific ordeals, that often ruin their lives and in plenty of cases cause them to commit suicide. They make it harder to people who have genuinely been raped. They tie up resources that could be used to investigate legitimate crimes. And that is why they must be punished exceptionally harshly.

If a man also goes on to commit suicide from a false rape accusation, I would say it should be prosecuted as murder. The outcome of false accusations is well known.

However awful, however evil the act of rape is, at the very least the justice system is on your side however hard it may be to get a conviction, given the "he said, she said" nature of most cases. A false accusation subverts this system maliciously, and this cannot ever be tolerated. These people need to know they will be punished.

And no, this obviously does not mean that if a person is found not guilty of rape that it was automatically a false accusation. There would still need to be a case proved the other way.
