While certain authorized personnel like SPG or PSOs accompanying VVIPs may be permitted to carry weapons under specific security protocols, the Sky Marshal’s primary role and operational requirement is to be an armed officer ready for immediate action during a flight. They are specifically authorized to carry loaded weapons accessible for use in the aircraft cabin to counter potential threats.

Sky Marshals are specifically deployed as armed security personnel on flights and are authorized to carry loaded weapons for the purpose of in-flight intervention.

Authorization for other personnel (like SPG or PSOs) to carry weapons on flights often involves different procedures, potentially including checked baggage or specific securing methods, whereas the Sky Marshal’s weapon is kept readily accessible.

Sky Marshals, being authorized security personnel, need to identify themselves as such to other security staff, airline crew, etc. The primary document for this identification is their official Identity Card issued by their parent organization (e.g., NSG or CISF, if applicable). While weapon authorization is necessary for them to carry a weapon, the security personnel at the checkpoint would primarily verify their official status via their Identity Card.

The official Identity Card is the key document checked by security personnel to confirm the status of a Sky Marshal.

Sky Marshals operate under strict protocols, and their identity and mission details are kept confidential. However, coordination with airport security requires proof of their official capacity.

Articles seized during the security screening of airline passengers are initially taken into custody by the security personnel who conduct the search. In India, this task is performed by the Airport Security Unit (ASU) or Airport Security Group (ASG), which are typically units of the CISF or State Police. These personnel are responsible for the handling, documentation, and disposal of seized items according to the procedures laid down by BCAS.

The Airport Security Unit (ASU) or Airport Security Group (ASG/APSU), comprising personnel from forces like CISF, are responsible for seizing and subsequently handling/disposing of prohibited articles found during passenger screening.

The disposal procedures vary depending on the nature of the item (e.g., legally prohibited weapons are handed over to police, liquids over limits might be discarded, less dangerous items may be returned or stored for collection).

In India, the Bureau of Civil Aviation Security (BCAS) is the regulatory authority for civil aviation security. While the Sky Marshals themselves are personnel from agencies like the NSG, their deployment schedule, including which flights are covered, is determined by the BCAS based on threat assessments and security requirements.

BCAS is the regulatory body that decides the deployment schedule and requirements for Sky Marshals on flights in India.

The actual Sky Marshals operating in India are typically commandos from the National Security Guard (NSG). The specifics of their deployment are classified for security reasons.

The National Institute of Criminology and Forensic Science (NICFS), now part of the National Forensic Sciences University (NFSU), is a premier institution in India for training and research in criminology and forensic science. It imparts training to a wide range of professionals involved in the criminal justice system, which includes Police Officers as well as Judicial and Correctional Service Officers.

NICFS provides training to personnel from various wings of the criminal justice system, including police, judiciary, and correctional services.

Apart from training, the institute also conducts research in relevant fields and provides expert services.

Which one of the following does not form a method of search for clues at scene of crime?

Spiral method

Crisscross method

Common crime scene search methods include the Spiral method, Strip or Line method, Grid or Crisscross method, Zone method, and sometimes the Wheel or Ray method. However, the Wheel method (B) is often considered less systematic or effective for thorough coverage compared to the Spiral, Strip, or Grid methods, especially in large areas. While it is sometimes listed as a potential method for radiating outwards from a central point, it is less universally applied or recommended for comprehensive searches than the others listed.

While Spiral, Strip, and Crisscross (Grid) are standard and widely used crime scene search methods, the Wheel (Ray) method is less common and potentially less effective for ensuring complete coverage, leading it sometimes not to be listed as a primary method.

Each search method has its advantages and disadvantages depending on the size and type of the crime scene, the number of personnel available, and the nature of the expected evidence.

Ketones, such as Acetone, are volatile organic compounds. While not explosives themselves, some are highly flammable and can be used as solvents or precursors in the production of various dangerous substances or even improvised explosives. Therefore, in a security context like aviation, they fall under the category of dangerous substances.

Ketones are classified as dangerous substances due to their flammability and potential use in synthesizing other hazardous materials.

Airport security regulations, such as those enforced by BCAS in India, list various categories of prohibited items, including explosives, dangerous articles, and dangerous substances (which include flammable liquids, corrosive materials, toxic substances, etc.). Ketones like acetone fit within the dangerous substance category.

TNT, or Trinitrotoluene, is a chemical compound used as an explosive. At room temperature and pressure, it exists as a solid crystalline substance, often yellow in colour.

The physical form of TNT under standard conditions is solid.

TNT is typically cast into blocks or flakes for military and industrial use. It melts at 80.35 °C (176.63 °F).

The detonator is used to initiate the main charge in a bomb or explosive device.

Detonators contain a small amount of sensitive primary explosive that, when initiated (e.g., by electrical signal, friction, or shock), creates a shock wave powerful enough to set off the less sensitive but more powerful main explosive charge.

An explosive train typically consists of an initiator (like a blasting cap or electric detonator), an optional booster (which may use a secondary explosive like PETN), and the main charge (which uses a bulk explosive like TNT, RDX, or ANFO). The detonator is the crucial first step in this sequence.

As per BCAS standards for X-ray machines used for security screening, a minimum pixel count of 1024 x 768 is typically specified for achieving adequate image resolution for threat detection.

The pixel count (resolution) of an X-ray machine determines the clarity and detail of the scanned image, which is crucial for operators to identify potential threats like weapons, explosives, or other prohibited items.

BCAS (Bureau of Civil Aviation Security) in India sets detailed technical specifications for security equipment used at airports, including X-ray baggage scanners, to ensure they meet required performance standards for effective threat detection.
