Timing is everything. Patrick Brown was judgemoored.
It means that every man in the world is vulnerable, not because he has necessarily misconducted himself, but because a woman may say he has. The truth of the alleged misconduct — did it happen? Were there mitigating circumstances? Does the accuser have motive to lie? — is incidental, if not irrelevant.
