However, no systems are fault free. Whether we are talking about computing systems, mechanical systems, or societal ones.
Sometimes police can arrest an innocent person before they realize the mistake and release them.
Should we stop policing completely? Or maybe the right question to ask is “how do we minimize the chance for police to make mistakes?”. Note, these are two separate issues:
1. Do we need the police at all?
2. How do we make police to not arrest innocent people all the time?
