Does art imitate life, or does life imitate art? Life is messy. And this week’s episode of “Bull” captured the essence of not only a messy life, but the angst that defendants experience when feeling wrongly accused.

Dr. Jason Bull, the charming yet slightly narcissistic psychologist who runs a state-of-the-art trial sciences firm, has once again found a criminal defendant who desperately needs his expertise. In fact, Dr. Bull must be feeling the holiday spirit because this time, he and his team work pro bono. (And yes, in case you’re wondering, real-life jury consultants do occasionally take on pro bono cases.)
