Many people that are protectors do join the force. But they're bullied off and intimidated by the bullies on the force who have far more seniority and the backing of the police union. Trying to speak out about the wrong doings of other police officers on the force has cost many good officers their career while the police who commit murder get a paid vacation and their job back. At worst they have to find a job at a new department which is never difficult for them. So yes, there are tons of people who would love to have such a job if proper oversight became a thing as well as the removal of many problematic officers.
