The ruling on adding other violations to a single violation

Question:
She performs wudu' (ablution) for whatever is upon her. The questioner in this case says: I stopped a person for a specific violation, then I found on him some other violations besides this one, which are not this rare case of renewing documents and searching. So, do I follow the first violation, or do I add the other violations?

Answer:
You are responsible for what you are responsible for; you are responsible for what you are responsible for. As for the violations for which you are not responsible, you are not required to look into them. Leave them to the others who are responsible for them.
