That's just not the job you're payed to do. Police, being selected from the populace at large, will have various competencies, attitudes and prejudices. You go to the call handle it and go to the next. That's what you're paid to do, that's the oath you take. Sometimes backing up another officer will be about making sure things are handled reasonably and don't run off the rails. If you can't take the heat get out of the oven.
