They will almost certainly release it at the time of his arraignment (is he having a preliminary hearing? do we know?)
And it will be released online for us, and if he's not on suicide watch, his lawyer will bring him a copy in his cell. At least, that's what we saw for Barry Morphew and Leticia Stauch (and others). I think that's pretty standard. Barry's affidavit was famously over 100 pages long and we all wondered if he ever read it all.
What I'm now confused about is the AA. I'm seeing two documents referred to: PCA and AA. Yesterday, someone posted that AA might remain sealed? Is that right? Will we only see the PCA?
