This section highlights the strategic significance of the Iron Dome in deterring aggression.
Need for a Code of police investigation
Context
In a recent judgment, the Supreme Court (SC) underscored the critical necessity for a “consistent and dependable code of investigation” to prevent deficiencies in police probes that might lead to the acquittal of the guilty on technical grounds.
About the SC Judgment
- The SC drew inspiration from the recommendations of the Malimath Committee on Reforms of the Criminal Justice System.
- This committee report highlights the significance of achieving successful prosecution, which hinges on a thorough and meticulous quest for truth and the collection of evidence that is both admissible and probative.
- The ultimate goal is to avert lapses in police investigations that could result in the exoneration of the guilty based on technicalities.
Malimath Committee
The Committee on Reforms of the Criminal Justice System was established by the Government of India, Ministry of Home Affairs, with a mandate to contemplate measures for overhauling the Criminal Justice System.
The committee’s terms of reference encompassed various aspects:
- Examination of Fundamental Principles: The committee scrutinized the fundamental principles of criminal jurisprudence, including constitutional provisions, to assess whether any modifications or amendments were necessary.
- Revising Legal Codes: In light of their findings on fundamental principles, the committee explored the need to revise the Code of Criminal Procedure, the Indian Penal Code, and the Indian Evidence Act to align them with contemporary demands and the aspirations of the Indian populace.
- Simplifying Judicial Procedures: The committee made specific recommendations to streamline judicial procedures, making justice delivery more accessible, expedited, straightforward, and cost-effective for the common citizen.
- Enhancing Synergy: It suggested ways to foster synergy among the judiciary, prosecution, and police, thereby reinstating public trust in the Criminal Justice System by safeguarding the innocent, supporting victims, and rigorously punishing wrongdoers.
- Case Management: The committee examined the feasibility of implementing a professional approach to managing case pendency at both investigation and trial stages, with a focus on holding the Police, Prosecution, and Judiciary accountable for delays.
- Federal Crime Concept: Additionally, it explored the feasibility of introducing the concept of “Federal Crime” into the Seventh Schedule of the Constitution.
Why Reforms in Police Probe System Are Necessary
- The state’s responsibility to protect the life, liberty, and property of its citizens necessitates suitable preventive and punitive measures, which also serve the vital purpose of preventing private retribution and maintaining peace and order in society.
- When the rights of citizens are violated, it becomes the duty of the state to apprehend the wrongdoer, ensure a fair trial, and, if guilt is established, administer punishment.
- Effective substantive penal laws can only be realized when the procedural laws that enforce them are efficient.
Structure of the Criminal Justice System in India
The Indian Criminal Justice System comprises government agencies responsible for law enforcement, crime adjudication, and correctional processes.
It can be divided into four subsystems:
- Legislature (Parliament)
- Enforcement (Police)
- Adjudication (Courts)
- Corrections (Prisons, Community Facilities)
Role of Police in the Criminal Justice System
- Within the Indian criminal justice system, three pivotal entities—the police, the prosecution, and the judiciary—play distinct roles.
- The police’s activities are integral to the administration of justice in criminal cases and significantly influence the functioning of the entire criminal justice apparatus.
- They are typically the first to engage with victims, witnesses, and suspects, playing a crucial part in the identification of suspects and establishing guilt during trial.
Challenges Faced by Police
- Lack of Trust: There is a pervasive lack of trust in the police and investigative agencies, impeding their effectiveness and undermining the rule of law.
- Custodial Interrogation Constraints: The police face limitations in custodial interrogation time (restricted to 14 days) when dealing with suspects. Extending and enhancing intermittent interrogation rights could facilitate more thorough investigations.
- Evidence Preservation: Police often lose crucial evidence due to inadequate tools, witness reluctance, and indifference. A technological and legal solution is imperative to systematically preserve evidence, including digital storage and improved evidence management within the court system.
Atto-Physics: new tools to fathom the World of Electrons
Context:
The 2023 Nobel Prize in Physics was awarded to Anne L’Huillier, Pierre Agostini, and Ferenc Krausz for their groundbreaking contributions to the field of attosecond science.
Their work has enabled the study of electron dynamics in matter at an unprecedented timescale of one quintillionth of a second, or 10^-18 seconds.
What is Attosecond?
- Definition: An attosecond is an extremely brief unit of time, equivalent to one quintillionth of a second (10^-18 seconds). It represents the timescale at which electron properties undergo rapid changes.
- Attosecond Science: Attosecond science, also known as attophysics, revolves around the generation of ultra-short light pulses and their utilization to investigate rapid processes involving electrons.
Atto-Physics: The Science Behind It
- High-Harmonic Generation:One of the foundational discoveries in attophysics, led by Anne L’Huillier and her colleagues, was the observation that passing an infrared light beam through a noble gas resulted in emitted light with frequencies that were harmonics of the beam’s frequency. This phenomenon, termed high-harmonic generation, laid the groundwork for attosecond pulse generation.
- Wave Mechanics:The production of attosecond pulses is rooted in wave mechanics. The emitted light arises from electrons gaining and losing energy as they interact with oscillating electric and magnetic fields within the light beam.
- Constructive Interference:Attosecond pulses are generated through constructive interference when the peaks of different overtones merge. Conversely, destructive interference occurs when peaks align with troughs, leading to signal cancellation.
Producing Attosecond Pulses
- Interference Combinations: Researchers manipulate interference combinations of multiple overtones to generate attosecond pulses with durations lasting only a few hundred attoseconds.
- Precise Frequency Range: Attosecond pulses are produced when the beam’s frequency falls within a specific plateau range, as dictated by interference effects.
- Measuring Attosecond Pulses: RABBIT Technique
Pierre Agostini and his colleagues developed the RABBIT (Reconstruction of Attosecond Beating by Interference of Two-photon Transitions) technique.
It involves measuring electrons ejected from noble gas atoms by attosecond pulses and a longer-duration pulse, providing insights into pulse properties, including duration.
Applications of Attophysics
Solar Power Enhancement: Attosecond studies have refined our understanding of the photoelectric effect, a fundamental process in solar power generation. Insights gained from atto-physics could potentially lead to advancements in solar technologies.
- Electron-Dependent Fields: Attophysics has a significant impact on various scientific disciplines where electron properties play a pivotal role, spanning across physics, chemistry, and biology. By studying electron behavior at attosecond timescales, researchers can unlock new possibilities and applications in these fields.
