Lecture Notes — Criminal Justice System: Definition, Police & Prosecution

1. Criminal Justice System (CJS) — Overview

CJS is the set of agencies and processes established by government to control crime and impose penalties on those who violate laws.
Core components/pillars: Police, Prosecution, Judiciary (Courts), Prisons/Corrections, and Probation & Parole services.
Objectives of the CJS:
- To prevent crime and maintain law and order in society.
- To apprehend, investigate, and prosecute offenders.
- To ensure a fair trial and dispense justice impartially.
- To punish/reform offenders and reintegrate them into society.
- To protect the rights of victims, witnesses, and the accused.
- To deter potential offenders through effective enforcement of law.

2. Police — Role and Functions

The Police is the first point of contact in the CJS; it is the investigative and law-enforcement arm.
Core functions:
- Maintenance of public order and prevention of crime.
- Registration of FIR (First Information Report) on receiving a complaint.
- Investigation of criminal cases — collection of evidence, arrest of suspects, recording of statements.
- Production of the accused before a magistrate/court within the legally prescribed time.
- Protection of life and property of citizens.
- Traffic control and regulation.
- Assistance to prosecution in building the case for trial.
Structure in Pakistan: organized provincially, headed by the Inspector General of Police (IGP) in each province, with a hierarchy down to Station House Officers (SHOs) at the police-station level.

3. Problems Facing the Police in Pakistan

Political interference in postings, transfers, and investigations.
Shortage of trained manpower and modern forensic/technological resources.
Corruption and lack of accountability at various levels.
Poor investigation quality — over-reliance on confessions rather than scientific evidence.
Overburdened police stations, inadequate logistics (vehicles, equipment).
Public mistrust due to alleged high-handedness, custodial abuse, and delays.
Lack of specialized training in cyber crime, forensics, and modern investigation techniques.

4. Police Reforms & Use of Technology

Proposed/ongoing reforms:
- Depoliticization of police through security of tenure for police officers.
- Separation of investigation wing from the watch-and-ward (law and order) wing.
- Establishment of specialized units (e.g., cyber crime wings, forensic units).
- Community policing initiatives to improve police-public relations.
- Capacity building and modern training academies.
Role of technology:
- Use of forensic science laboratories for scientific evidence collection (DNA, fingerprinting, ballistics).
- Computerized crime record management and databases (criminal record systems).
- CCTV surveillance and safe-city projects in major urban centers.
- Use of geo-tagging and digital case-tracking systems to monitor investigation progress.

5. Prosecution — Role and Functions

The Prosecution is the legal arm that represents the State in criminal proceedings.
Core duties of Public Prosecutors:
- Scrutinize the police investigation/challan (charge sheet) before filing it in court.
- Advise the police on the legal sufficiency of evidence during investigation.
- Represent the State in court, present evidence, examine and cross-examine witnesses.
- Ensure that the trial proceeds in accordance with law and that justice is served — for the State as well as being fair to the accused.
- Decide whether to pursue, withdraw or compound (settle) a case within legal limits.
In Pakistan, the Prosecution Service was established as a separate department from the police (Prosecution Service Acts in various provinces) to bring more professionalism and objectivity into case-building and trial conduct.

6. Problems Facing the Prosecution in Pakistan

Shortage of trained prosecutors relative to caseload.
Weak coordination/communication between police (investigators) and prosecutors.
Poor quality of police investigation and evidence handed over to prosecution, weakening cases in court.
Political and administrative interference.
Low conviction rates due to weak evidence, witness hostility/intimidation, and delays.
Lack of resources, forensic support and modern case-management tools.

7. Trial and Conviction Process (Overview)

Sequence: FIR registration → Investigation → Submission of challan/charge sheet → Framing of charge by the court → Recording of prosecution evidence → Statement of the accused → Defense evidence → Arguments → Judgment (conviction/acquittal) → Sentencing (if convicted) → Right of appeal.
Standard of proof in criminal trials: guilt must be proved beyond reasonable doubt.
Key issues affecting trial and conviction:
- Case backlog and prolonged trials.
- Witnesses turning hostile due to fear, bribery or lack of protection.
- Weak scientific/forensic evidence base, over-reliance on eyewitness testimony.
- Low conviction rates in serious crimes, contributing to public perception of impunity.
