Erie County District Attorney’s office:
Reporting that evidences this incident of police violence is right here.
Demand that the officers who committed these crimes are charged and prosecuted. Demand that their commanding officer is investigated for whether assault on peaceful protesters was ordered, either formally or informally.
The DA’s office cannot rely on the police to investigate a crime the police themselves committed. They must make an independent decision to charge and prosecute. They have video evidence, witnesses, and a victim.
This is not asking the DA’s office to do anything special. This is expecting them to do their job.
