3. Law & Order
While we can't fully endorse a police force that employs Ice-T as a working cop, Law & Order is the go-to show for those who want to learn more about law and order and the franchise has been going strong for nearly 25 years. That driving bass and rock guitar...perfect.
2. True Detective
Easily one of the best modern cop shows, this opening took quite a lot of thought. Directed by Sydney-based Creative, Patrick Clair, the use of double-exposure photography and slow-motion produces an other-worldly effect while hinting at the show's greater themes. Alternative-country band, The Handsome Family, supplied a song absolutely rife with creepiness and mystery to start off a series that left us all on the edge of our proverbial seats.
