The Law Enforcement Sourcebook for Cyberpunk
Protect & Serve isn't just about creating a cop character. It's about creating a 'cop campaign'. It's about the live and times of a police officer from their perspective and not from the street.
The book does talk about 'the streets, but goes right into the laws and enforcing them. There is a section on the 'bad guys' that might hinder them, from gangs to organized crime.
Then of course a section from the other side. What happens when you get arrested.
Finally a section on how to run a 'Law Enforcement' Campaign.
There are dozens of scenario ideas, but to be cautious, these are purely ideas and have nothing really fleshed out. Only a few paragraphs on each.
