Shortly after David Brown was sworn in as the Dallas Chief of Police, his son shot and killed a police officer. Just before he retired as chief, 5 Dallas officers were shot and killed in what was said to be the deadliest attack for law enforcement since September 11th, 2001. Today on the show, we ask David Brown how he's changed after 33 years of policing. Criminal is a proud member of Radiotopia from PRX. If you haven't already, please review us on iTunes!
