Do police officers have a lot of affairs?

Cheating is not specified or pertaining to a particular group, colour, race, job, gender etc. People that do cheat personally make the choice to do so. As above, no more so than any other profession. On the job stress can strain home and family life but most officers have high moral standards or they wouldn't do what they do everyday. Those with families often find that home with loved ones is the only place they can feel safe and comfortable and do everything they can not to put that in jeopardy.
