I think her quote means something to the effect of - everyone everywhere is freaked out about sexual predators, to the point some want to kill them. But here we have a sex predator as an FBI informant.
And if that is her point then she is correct (among other reasons why informants many times backfire).
No, she’s not saying that. She’s saying the FBI informant is a predator and as bad as a sexual predator because he got her darling adult baby boy’s confidence and then turned him.
