Criminal Justice System | Law Enforcement Pillar

Criminal Justice System (CJS) Framework
📌 The CJS is defined as the sum total of concerted efforts of government agencies aimed at the prevention and suppression of criminality.
👮 The CJS is structured around five pillars: Law Enforcement, Prosecution, Court, Correction, and Community, arranged in chronological order based on an offender's contact with the system.
⚙️ Core functions of the CJS include enforcing laws, safeguarding individual rights, detecting/investigating crime, punishing violators, and rehabilitating/reintegrating convicted offenders.

Law Enforcement Pillar Agencies and PNP History
🌐 Major agencies under the Law Enforcement pillar include the Philippine National Police (PNP), National Bureau of Investigation (NBI), Philippine Drug Enforcement Agency (PDEA), Bureau of Immigration and Deportation (BID), and Bureau of Customs (BOC).
🏛️ The PNP was established under Republic Act 6975 (1990), succeeding the Integrated National Police (INP) created by PD 765, and is mandated to be national in scope but civilian in character.
🔄 The PNP was further reformed by Republic Act 8551, which notably raised the minimum educational qualification for appointment from 72 units to a Bachelor's degree.

Police Arrest Procedures and Rights
🛑 An arrest is defined as taking a person into custody to answer for an offense, enforceable via warranted arrest (judicial order) or warrantless arrest (e.g., *in flagrante delicto* or hot pursuit).
⏱️ A warrant of arrest generally does not expire, but execution must be reported within 10 days of receipt.
🗣️ During custodial investigation, the Miranda Rights (right to remain silent, right to counsel, right to be informed of the accusation) must be explained elaborately, not recited, and any waiver of the right to remain silent must be in writing and in the presence of counsel.

Search Warrant Procedures and Legal Doctrines
📝 A search warrant requires probable cause determined personally by a judge after examination under oath, and must specifically describe the place to be searched and things to be seized.
🚪 The Knock and Announce Rule requires officers to announce presence, identify themselves, show the warrant, and explain it in a known dialect before entry.
🔭 The Fruit of the Poisonous Tree Doctrine dictates that evidence derived from an illegal search (or illegal means) is inadmissible in court.

Regulatory Period of Detention
📅 The maximum period for detention without filing formal charges is governed by the penalty of the crime:
* Light Penalties (Imprisonment $\le 30$ days): 12 hours
* Correctional Penalties (Imprisonment from 6 months and 1 day to 6 years): 18 hours
* Afflictive or Capital Penalties ($\ge$ Reclusion Perpetua): 36 hours

Key Points & Insights
➡️ The law enforcement pillar acts as the "frontliner" of the CJS, responsible for crime prevention, detention, investigation, and assisting in prosecution.
➡️ The NBI is often called the "law enforcement of last resort," generally taking over cases that are sensational or of great national interest, forwarding standard complaints to the PNP.
➡️ Police officers have the authority to summon any person for assistance during a lawful arrest and may break into a building if admission is refused after announcing authority and purpose.
➡️ A key exemption to the warrantless arrest rule is that suspicion alone is not ground for *in flagrante delicto* arrest; an overt act indicating the crime must be committed in the officer's view.
