It is up to each of us to be vigilent in Charity for the souls of all involved.
Admonishing sinners, Instructing the Uniformed, and Counselling the Doubtful are all Spiritual Works of Mercy.
As stated in other threads, when a Catholic publically and seriously violates Catholic teaching within a particular Diocese, contact the Diocese Bishop (if it can not be handled by your Pastor).
This includes Catholic hospitals, Catholic universities, Catholic politicians, all Catholic organizations, Catholic Parishes, etc.
If the Bishop does not correct the abuse, contact the Vatican with a copy to the offending Bishop, and the Papal Nuncio assigned to that Country.
Also as stated previously, neither Bishops nor the Vatican are mind-readers. Do not expect them to know everything that goes on all the time. Do not ASSUME.
