Unfortunately there isn't anybody else to turn to for matters like this... Which is also probably why Gaetz dropped the name on air.
Gaetz understands nothing will be done about it by the FBI, but he can make this fool's life a bit harder by putting turning the spotlight on him. Exposure itself can be akin to imprisonment and death for people who engage in behavior like that... I imagine we'll be seeing posts before too long where some autist found something after diving into this McGee's history.
