Bart Ganzel's lawyer (season 13/14 spoiler)

does anyone remember this lawyer? barry?

i just rewatched Undercover Blue, where he defended Cassidy when he was accused of rape - how was he allowed to do that considering how involved he was with Ganzel?

Ignoring the strange concept that he was even allowed to continue practicing law, I'm shocked that he was also allowed to defend Cassidy on this kind of charge...and why did nobody say anything during the episode?? i have so many questions. am i just confused??
