Yes. I did more research than I ever wanted to and saw some things I wish I didn't. I went on ride-alongs spent time with Homicide Cold Case and SVU detectives hung out in subways learning how to spot pervs and pick-pockets viewed an autopsy went to a police firing range and witnessed court cases and I read read read.
Having a college degree gave me the opportunity to be... well-rounded. Also the people I met at the university most of them are still my colleagues now. People I've known for years are all in the industry together.
