Not necessarily.
When John Brown raided the arsenal at Harpers Ferry in 1859, it took very little detective work to find the money trail that supported him. It led to prominent Boston abolitionists.
As soon as they were unmasked, they declared themselves insane and took up residence in an asylum, thus avoiding prosecution.
Mueller may be doing the same thing.
I’ve read that Mueller has been living in a memory care facility for years. How clever of him to have established his cover so long ago!
