Police and Law Basics for Constable Aspirants

1. The Police System in India and Karnataka

A police constable is the first face of the law for most citizens. To do the job well, and to answer exam questions, you should know who controls the police, how the Karnataka State Police is organised, and what the different wings such as Civil Police, DAR and KSRP do.

Police is a State subject

• The Constitution divides subjects between the Union and the States in the Seventh Schedule.
• 'Public order' (Entry 1) and 'Police' (Entry 2) are in List II, the State List. So each state makes its own police laws and runs its own police force.
• The Union Government has its own Central Armed Police Forces (such as CRPF, BSF, CISF) under the Ministry of Home Affairs (MHA). States can request their help.
• The Indian Police Service (IPS) is an All India Service. IPS officers are recruited by the UPSC and allotted to state cadres, where they hold senior posts.
• In Karnataka, the main state law for the police is the Karnataka Police Act, 1963.

Structure of the Karnataka State Police

• The head of the state police is the Director General and Inspector General of Police (DG & IGP), with headquarters in Bengaluru. The force works under the State Home Department.
• Large cities have Police Commissionerates headed by a Commissioner of Police, for example Bengaluru City, Mysuru, Mangaluru, Hubballi-Dharwad, Belagavi and Kalaburagi. In October 2026 the state approved splitting Bengaluru city police into five commissionerates in phases; check the current status.
• Outside commissionerates, districts are grouped into police ranges, each usually led by an Inspector General of Police (IGP).
• Each district is headed by a Superintendent of Police (SP). Districts are divided into sub-divisions (Deputy SP), circles (Circle Inspector) and police stations.
• A police station is usually in charge of a Police Inspector or a Police Sub-Inspector (PSI), called the Station House Officer (SHO).

Ranks, insignia and wings

• Ranks from bottom to top: Police Constable, Head Constable, Assistant Sub-Inspector (ASI), Sub-Inspector (PSI), Inspector, Deputy SP, Additional SP, SP, DIG, IGP, Additional DGP, DGP.
• In cities, some ranks have different names: Assistant Commissioner (ACP) is like Deputy SP, and Deputy Commissioner (DCP) is like SP.
• Insignia basics: an ASI usually wears one star, a Sub-Inspector two stars and an Inspector three stars. Senior IPS ranks use combinations of the State Emblem, stars, and a crossed sword and baton. Exact badge details follow the state uniform rules.
• Civil Police (CPC) handle station work: beats, patrol, complaints, investigation support and traffic.
• District Armed Reserve (DAR) is the armed wing of each district. It provides guards, escorts and reserve force for bandobast (security arrangements).
• Karnataka State Reserve Police (KSRP) is organised in battalions. It is sent across the state for law and order, riots, festivals, elections and disasters.

112: one number for emergencies

• 112 is India's single emergency number under the Emergency Response Support System (ERSS), a scheme supported by the MHA.
• One call to 112 can bring police, fire or ambulance help. Karnataka uses 112 for police emergency response vehicles.
• Help can also be sought through the 112 India mobile app (with an SOS button) and other channels listed on the ERSS website.
• Other useful numbers: 1930 (cyber fraud), 1098 (Childline), 181 (women helpline in many states).

💡 Learn the rank order from Constable to DGP as one sentence and say it aloud daily. Rank order and the meaning of short forms like SHO, DAR and KSRP are common easy marks.

2. The New Criminal Laws (in force from 1 July 2024)

On 1 July 2024 three new laws replaced the colonial-era criminal laws of India. Every constable now registers cases, arrests and collects evidence under these new laws, so exam papers ask about them often.

The three laws at a glance

• Bharatiya Nyaya Sanhita, 2023 (BNS) replaced the Indian Penal Code, 1860 (IPC). It defines crimes and punishments. It has 358 sections.
• Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) replaced the Code of Criminal Procedure, 1973 (CrPC). It explains procedure: FIR, arrest, investigation, bail and trial. It has 531 sections.
• Bharatiya Sakshya Adhiniyam, 2023 (BSA) replaced the Indian Evidence Act, 1872. It explains what evidence is accepted in court. It has 170 sections.
• All three were passed by Parliament in December 2023 and came into force on 1 July 2024.
• Offences committed before 1 July 2024 are still charged under the IPC, and cases already pending on that date continue under the old procedure (BNSS Section 531).

Important changes in BNS

• Community service has been added as a new kind of punishment (Section 4) for some minor offences, for example a first-time theft of property worth less than Rs 5,000 when the property is returned.
• Offences against women and children are grouped together in one chapter (Chapter V).
• New offences include organised crime, terrorist act, snatching, and murder by a mob (mob lynching).
• The old offence of sedition (IPC 124A) is not in BNS. Section 152 now deals with acts endangering the sovereignty, unity and integrity of India.
• Murder is defined in Section 101 and punished under Section 103 of BNS (punishment was Section 302 in IPC).

Important changes in BNSS and BSA

• Zero FIR (BNSS Section 173): a person can report a cognizable offence at any police station, whatever the place of the crime. The case is then transferred to the station with jurisdiction.
• e-FIR: information can be given by electronic communication. It is taken on record when the informant signs it within three days.
• Search and seizure must be recorded by audio-video electronic means (Section 105). For offences punishable with seven years or more, a forensic expert must visit the crime scene (Section 176).
• Police must inform a relative or friend of the arrested person, and a designated officer must display details of arrested persons at every police station and district control room.
• Under BSA, electronic and digital records (emails, server logs, phone data) are treated as documents and can be primary evidence.

💡 Make a three-column table: old law, new law, number of sections. Example: IPC to BNS (358), CrPC to BNSS (531), Evidence Act to BSA (170). Many MCQs only test these pairs.

3. Citizens' Rights and Special Laws

Police power must always respect the rights of citizens. The Constitution, the Supreme Court and many special laws set clear rules. A constable who knows these rules protects people better and avoids mistakes.

Fundamental rights linked to policing

• Article 20: no punishment under a law made later (no retrospective criminal law), no double punishment for the same offence, and no person accused can be forced to be a witness against himself.
• Article 21: no person shall be deprived of life or personal liberty except according to procedure established by law.
• Article 22: an arrested person must be told the grounds of arrest, may consult a lawyer, and must be produced before the nearest magistrate within 24 hours (excluding travel time).
• D.K. Basu v. State of West Bengal (Supreme Court judgment of 18 December 1996): officers making an arrest must wear clear name tags, prepare an arrest memo attested by a witness, inform a relative or friend, and arrange medical examination.
• Many of these arrest safeguards are now written into the BNSS itself.

Laws protecting women and children

• POCSO Act, 2012 (Protection of Children from Sexual Offences): protects every person below 18 years. Special courts and child-friendly procedures are used.
• Protection of Women from Domestic Violence Act, 2005: covers physical, sexual, verbal, emotional and economic abuse at home. Protection Officers help victims.
• Dowry Prohibition Act, 1961: giving, taking or demanding dowry is an offence.
• Childline 1098 helps children in need. The identity of child victims and of rape victims must never be disclosed.

Other special laws

• Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989: punishes atrocities against SC and ST persons, with special courts.
• NDPS Act, 1985 (Narcotic Drugs and Psychotropic Substances): controls drugs; punishment depends on small, commercial or in-between quantity.
• Motor Vehicles Act, 1988 (amended in 2019 with much higher fines): with its rules, it requires a driving licence, vehicle registration, insurance and a valid PUC certificate.
• Road safety: helmet for rider and pillion on two-wheelers, seat belts in cars, no drunk driving, no mobile phone use while driving. Good Samaritans who help accident victims are protected by law (Section 134A of the MV Act, added in 2019).
• Information Technology Act, 2000: covers cyber crimes such as hacking, identity theft and online cheating. Report cyber fraud at 1930 or cybercrime.gov.in.

💡 Exam questions love the year of each Act. Write the Acts in time order on one card: 1961 Dowry, 1985 NDPS, 1988 MV, 1989 SC/ST, 2000 IT, 2005 DV, 2012 POCSO.

4. Public Service Skills: First Aid, Disasters and Conduct

Police are often the first to reach an accident, a fire or a flood. Basic first aid, knowledge of disaster agencies and good conduct help save lives and build public trust. This lesson gives general, safe guidance only; formal first-aid training is always better.

First aid basics

• First check that the scene is safe for you, then call 112 for help.
• CPR for an adult who is unresponsive and not breathing normally: push hard and fast in the centre of the chest, about 100 to 120 compressions a minute, about 5 to 6 cm deep. Trained rescuers give 30 compressions then 2 rescue breaths.
• Bleeding: press firmly on the wound with a clean cloth and keep pressing until help arrives.
• Burns: cool the burn under clean running water for about 20 minutes. Do not apply ice, butter or toothpaste. Cover loosely with clean cloth.
• Do not move a person with a possible neck or spine injury unless there is danger such as fire.
• Note the 'golden hour': getting proper medical care in the first hour after serious injury gives the best chance of survival. The MV Act also uses this term.

Disaster management

• The Disaster Management Act, 2005 set up the National Disaster Management Authority (NDMA), chaired by the Prime Minister.
• Each state has a State Disaster Management Authority (SDMA) chaired by the Chief Minister, and each district a DDMA chaired by the Deputy Commissioner (District Collector).
• The National Disaster Response Force (NDRF) is a specialised force for rescue. States have their own State Disaster Response Force (SDRF).
• Police help with evacuation, traffic control, crowd management, protection of property and passing on official warnings.

Communication, conduct and gender sensitivity

• Listen patiently, speak politely and use the local language (Kannada) clearly. Never use abusive words.
• Treat every person equally, whatever their religion, caste, gender, wealth or language.
• Women complainants should be treated with dignity; a woman officer should be present where the law requires. Never blame the victim.
• Be honest: refuse bribes and gifts. Corruption is a punishable offence and destroys public trust.
• Be respectful to elderly people, persons with disabilities and transgender persons, and keep personal information confidential.

💡 For first-aid questions, choose the safest and simplest answer: check safety, call 112, press on bleeding, cool burns with water. Options with ice, butter or moving an injured neck are always wrong.
