Bruce being selected for jury duty isn't a coincidence. I think he has worked it so he can be on the jury for Freeze's trial. Maybe because he realizes he overstepped the mark during his apprehension of him and is trying to rectify it. But I suspect there is more at play here. I am amazed they continue to hold trials in Gotham. There is no way they could find an impartial jury (this issue highlighted that fact.) I mean, they didn't even consider the evidence. They just came to the conclusion Mr Freeze probably did do it.
Curious to see how this one turns out.
