What Module III Asks

In one line

Module II asked how an offence is proved; Module III asks how it is stopped, deterred or detected before proof begins.

In the wording a student can write in an exam: the University's printed topic for Module III is "Modern Scientific Methods of Crime Control and Prevention", and the two nouns are not synonyms: prevention means stopping an offence from occurring, by removing the opportunity, by raising the risk of detection or by making the act harder; control means containing crime that does occur, by identifying offenders quickly, by recovering evidence, and by making the consequences follow reliably; and the module therefore covers the devices and systems that do those things, being the techniques of interrogation and their constitutional limits, surveillance and recording, biometric identification and the national databases, screening and detection equipment, communications and location evidence, and the methods of designing crime out.

The distinction, and why the syllabus makes it

Prevention operates before the offence. A camera at a junction, a metal detector at a court entrance, a lock that cannot be forced, a street that is lit. Its measure of success is that nothing happens.

Control operates after. A database that identifies a repeat offender, a network that connects two States, a technique that produces evidence.

Detection, which the syllabus does not name, sits between them and is what Module II is largely about.

Why the distinction earns marks. A candidate who writes about laboratory techniques in this module has answered Module II again. The University has already asked about the laboratory; here she is asking about the systems, and an answer built on that difference is the right answer.

What the module contains

The three techniques and their constitutional limits. Narco-analysis, the polygraph and brain electrical activation profiling. They are placed here rather than in Module II because they are methods of investigation rather than divisions of a laboratory, and because the University sets them here.

Surveillance and recording. Closed circuit television, facial recognition, number plate recognition, drones, and the recording obligations the Sanhita now imposes.

Biometric identification and the databases. The Criminal Procedure (Identification) Act, 2022, the Crime and Criminal Tracking Network and Systems, the Inter-operable Criminal Justice System, and the automated fingerprint system.

Screening and detection equipment. Metal detectors, baggage scanners and the portable bomb sniffer.

Communications and location. Interception, call data records, mobile device forensics, and the tracking of vehicles.

Electronic records in evidence, because none of the above is useful unless the record is admissible.

And the preventive methods that are not devices at all, being situational crime prevention and the design of places.

Why the University sets it

Three of her ten printed papers ask for the devices in the imperative: "Enlist modern devices in crime control and prevention. Explain any three of them in detail." Two more ask "Explain the use of different modern devices in crime control and prevention", and one asks about "modern techniques of crime control", separately from the devices. The 2019 paper asks about "modern of crime control", which is a misprint of the same question.
