I can't think of a case where the arrest happens after testifying.
I personally am losing hope that she is going to be charged. I am just holding onto the hope that if she is not charged, all of my assumptions (based on MSM reporting) about her level of involvement are wrong.
If not. If she was involved to the extent I believe, it will be a travesty that she gets away with standing back and watching a beautiful young mother's life get taken away, and goes so far as to help with the cover up.
It is just taking too long, in my opinion. The only thing I can think of is that LE is holding everything so close to their chest they don't want to arrest KK yet, because the DA would have very little reason to get the arrest warrant sealed etc. Then stuff about the case leaks out. Seems like weak rationale to me, and so I am worried an arrest won't ever happen.
