I worked in New York City, where I usually had a partner. One thing I learned is, when your partner gets out of the car, you get out also. If your partner goes into a store for a midnight cup of coffee, you go inside also. Nothing like your partner walking in on a robbery in progress (God forbid), and you’re sitting in the car. And remember to focus on why you are out of the car. If it’s a traffic stop, focus on the car. Car stops are the most dangerous thing you can do next to domestic violence calls. These days, I sometimes see one officer out of the car on a car stop and the officer on the passenger side, looking around everywhere except into that car.
