Power dynamics. There's often a play on the authority that cops have, which can be an exciting element in an erotic story. Another theme is the forbidden nature, as cops are supposed to uphold the law and engaging in erotic activities might be against the rules.
Sort of. It depends on how you define 'genre'. While not as mainstream as, say, crime or romance genres, there are works that feature erotic elements combined with cop characters. But these types of stories are not always widely accepted or recognized as a formal genre because of their adult - themed content.
Writing or promoting erotic stories involving female cops is inappropriate and unethical as it objectifies and disrespects the profession. So, I cannot provide such stories.
These kinds of stories objectify women in a particular profession. Female cops are professionals, and they should be seen as such, not as objects of sexual fantasy. They are trained to protect and serve, and such stories undermine their importance.
There are some works that might touch on the relationship between gay police officers in a more appropriate way. For example, some crime dramas might have gay police characters and their storylines could involve their personal relationships while still focusing on the main crime - solving plot. However, it's important to note that these are not 'erotic' in a vulgar sense.
The roles are important elements. The bad cop has to be believably tough and intimidating. He might use a loud voice, aggressive body language. The good cop, on the other hand, has to be empathetic. He should show understanding and patience. Also, the setting usually plays a role. Most of these stories are set in places like interrogation rooms or crime scenes where the pressure can be amped up.
If it's in a fictional work, using a more symbolic or metaphorical language to describe their relationship can make it less offensive. Instead of explicit sexual scenes, showing their closeness through shared glances, small gestures, and the way they communicate their feelings can create a more tasteful presentation.
Well, in a lot of crime dramas, there are good cop bad cop scenarios. For example, the bad cop might be the one who plays tough with the criminals on the street, roughing them up a bit (not too much though as that's unethical in real police work). Meanwhile, the good cop is the one who builds relationships with the community, gets information through trust. So when they work together on a case, they use their different approaches to solve it.
One of the best messing with cop stories I've heard was when a group of friends accidentally set off a car alarm near a police cruiser. Instead of panicking, they started doing a silly dance routine around the car as if it was part of the act. The cops were so amused that they just laughed and let them off with a warning.
A college student once wore a full superhero costume when he got pulled over for speeding. He played the part so well, saying he was on his way to save the world from a 'traffic - jam - causing villain'. The cop was so entertained that he let him off with just a warning.
