The courtroom stuff was bad. No attorney is going submit a photo into evidence immediately after getting the photo. And then to just buy the alibi? No, “Hey, maybe we should see if that guys father is alive or died of ALS.”? Just, “damn, that didn’t work. Oh well.”
Then you have Iris, who’s ostensibly a reporter, get what’s basically a confession out of the wife, and she didn’t think to record her? (Maybe in Central City you need both parties consent?) It would have been an interesting wrinkle to have the wife screw things up by not thinking ahead.
