What are 2 Questions That Will Never Be Answered Concerning the Nashville Shooter?

The manifesto of the Nashville shooter is not important to me. But 2 questions need to be answered by the FBI. 1, police said she planned this for months, we need details. 2, as a transgender how much testerone was she on. I realize that when a mass shooting takes place the only issue we can talk about is guns, but I’m gonna need a little more.
