Yes. Abuse cases should be handled locally. Oh, a report should be sent to Rome, and possible appeals go there, but there is no reason for the CDF to adjudicate every case.

Of course, this is assuming that the bishops care to act. If it can be shown that a bishop did not act to deal with a sexually abusive priest, the civil authorities should go after the priest under the sexual assault laws, with the bishop being charged as accessory after the fact.
