Police Accountability In Criminal Investigations
🔍 What Is Police Accountability?
Police accountability refers to the legal responsibility of police officers and forces to follow the law during investigations, and to be held liable when they abuse power, violate rights, or act negligently.
This includes:
Unlawful arrests or detention
Fabrication of evidence
Use of excessive force
Failing to disclose exculpatory evidence
Racial profiling or discrimination
Breaches of suspects’ rights under laws like PACE (UK) or constitutional protections (e.g. 4th & 14th Amendments in the US)
🚨 Key Legal Principles
Police are not above the law — they can be sued or prosecuted.
Accountability can be:
Criminal (e.g. perjury, assault)
Civil (e.g. wrongful arrest, negligence)
Disciplinary (internal police standards)
Courts also exclude evidence ("fruit of the poisonous tree") if obtained unlawfully.
