Interesting episode and premise, i like the idea of the gunshot detection system.
It was so cool to see Michele as a guest star, i had no idea that she was going to be on it and had to do a double take when i saw her
It was nice to see her and Jonny on the same show although they barely had any scenes together.

I might be in the minority here but i am not really a huge fan of Shinwell and i find it hard to see what they are trying to do with the character(especially after the reveal at the end of the ep). It seems like they are leading somewhere but it is unclear where or why. Are we supposed to like him or not?
