Did DA Boudin just take credit for the operation that was started before him?

Answer

No. DA Boudin created, launched, and implemented Operation Auto Pilot.   One suspect arrested in the operation, Quoc Le, did have previous charges before DA Boudin. Those were separate charges and remain pending–the prior administration failed to secure a conviction and he was out on bail (a reminder of why bail is bad policy). DA Boudin has filed many new felony charges on this new operation.
