That's the key bit. They don't need to be proven right. They don't even need their story to be consistent.
> “Never believe that anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.” > ― Jean-Paul Sartre
I will say though that I am also a bit scared. When government officials push a blatantly false narrative, that they know is a lie, and their supporting voters completely accept that version of reality over what they can see with their eyes, it suggests that those same voters would be okay with ANYTHING the administration does.
They should augment deployed enforcement with those who have such expertise.

Without obscuring how bad is it, I don't believe there was ever a time when officials _didn't_ rush to defend federal officers without waiting for key facts to emerge. The us government has constantly loved to say that no one working for them has done anything wrong.
