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.
O Death rock me asleep bring me to quiet rest let pass my weary guiltless ghost out of my careful breast.
