I'm writing a WIP novel with a rookie police officer. I'm concerned that the situation is incorrect / impractical / unbelievable:
He is, respectfully, a minor character and his story is used to serve as a "mini mystery" to add realism, clues, exposition for the later chapters, which helps build the foundation of a larger tale.
He is starting the night shift on his own, as a rookie. (if not realistic, maybe because of scheduling mishap?)
It is his first night on the job. First time out of training.
He is a "state" trooper. A rural police officer. Not a city cop.
Events take place during 1 night, on the outskirts of the city.
He meets up with the "sheriff / higher ranking officer" later on, as the plot thickens.
Starting place: Parked in his car, on the side of the highway. Doing highway patrol.
Where can I locate resources that would let me check all this? How do I do background research that will help me?
