I found it ridiculous the Dominator forced the execution of this guy. That removed all the chances of the criminal actually revealing anything under normal interrogations. It's probably nothing but on another sign how absolutely reliant the society has become on the Sibyl system and computer jazz. They feel like they don't really need to do any old-fashioned police work (Gino is a perfect example of this, always relying on the most obvious solutions and then left cursing when it didn't work like the textbook said).

Akane is objectively speaking blaming herself too much. She's totally fresh out of school and I got the feeling she might have been the honours student type in good and bad: Believing everything she read (and reading a lot). I think that was partially proven by how quickly she was going to check the book Masaoka mentioned; as if that was the important point, not what he was saying. So, now in practical work she's going to be lost for a while, because I assume she's not the genius type who would have completely internalized everything she read and being able to combine it all on the spot, adapting it all to formulate new theories. To mention Gino again, I think he's ended up to the same place out of his own free will: To spare himself and his psycho-pass, he stopped thinking and feeling and only relies on basic concepts out of the books.
