Honest question looking for an honest answer.

"Trust, but verify" is well-regarded modus operandi. Why is it acceptable in other circumstances but not this one?

If "trust, but verify" can be a legitimate threat mitigation strategy, how does one conduct the verification in good faith and avoid such verification being labeled as being an "attempt to discredit"?

I honestly don't see how rape differs from any other accusation of wrongdoing with respect to due process. Is it not the right of the accused to question the accounts of their accuser and conduct their own investigation?
