They are trying to set him up. Janet may or may not know, certainly Atty Gen Eric Holder knows. They want a federal case to charge him with.
If Sheriff Joe gets railroaded,
the feds have to know that it’s “put up or shut up” time

IE, they will know that this can either trigger a civil war
or that they can walk all over us without reaction.
I’ll bet Janet’s sensible shoes that she knows.
