Why do I ask this? Well, apparently it took the FBI over 13 months after being notified of Larry Nassar's crimes to actually get anything going. John Manly, lawyer for many of Nassar's victims, notes as well that his office's (clients') requests for meeting (to give them evidence) were refused, and that in his opinion, the investigation appears to have been slow walked by both the FBI and U.S. attorneys. Obviously, they've got some speeding tickets to issue or something.
Of course, those who have been watching the FBI lately are keenly aware that there are a number of things more important to the FBI these days than investigating obvious crimes, like pinning false accusations of Russian collusion on President Trump (or nailing him with a Mickey Mouse allegation from one of his former staffers), ignoring Hilliary's corruption, and the like. Actually issuing a subpoena or warrant on an obvious case, or even sending a note to local police forces so they could get an investigation started, simply didn't fit the model.
Ugly reality is that this is going to get worse and worse. It hit MSU hard (rightly so), it's hitting USAG and the USOC hard, and now the list of culprits is extending to the FBI, U.S. attorneys, local police forces, and the like. Next up: Nassar's former employers at Wayne State University, the University of Michigan, and his high school. The University of Michigan is an interesting case, since I'd suspect Nassar had something of a fixation or fetish for female gymnasts, but he worked with the football and track teams there. One has to wonder whether they knew, or suspected, something even then.
