Would you help me with my Administration of justice class questions?

The text mentions the concepts of “police personality” and the “police subculture”

1. What is the police personality? Are people with these personality traits drawn to police work or do these traits develop after someone has been on the job for awhile?
2. What about the police subculture? What is it? Why does it exist?
3. How do the police subculture and police personality impact community relations, both in a positive and negative manner?
