Mixed Deck — All FBI Topics Flashcards

When intelligence suggests a target may be planning an imminent attack, an FBI surveillance team should prioritize:

Answer: Notifying supervisors and preparing for potential intervention while maintaining coverage

Imminent threat indicators require balancing continued intelligence collection with readiness for protective or arrest action, always with supervisory notification.

What does 'sympathetic fire' mean in the context of FBI shooting psychology?

Answer: Unintended discharge when one hand tenses in response to the other hand clenching under stress

Sympathetic fire occurs when tension or startle in one hand involuntarily triggers clenching in the other hand (including the gun hand), potentially causing an unintended discharge.

An FBI agent uses deadly force to stop a fleeing felony suspect. Which legal doctrine most directly governs this action?

Answer: The Fleeing Felon Rule under Tennessee v. Garner

Tennessee v. Garner (1985) held that deadly force against a fleeing felon is only constitutional if the suspect poses a significant threat of serious physical harm.

What is the primary purpose of including a pull-up or flex-arm hang event in law enforcement physical standards?

Answer: To measure upper-body pulling strength needed to climb, vault, and scale obstacles

Pull-up strength reflects functional upper-body power required to scale fences, climb, and perform tactical vaulting in the field.

An FBI agent arrests a suspect without a warrant in a public place based on probable cause. This is lawful under which principle?

Answer: The public arrest exception — warrantless arrests in public are constitutionally permissible with probable cause

The Supreme Court has held that a warrantless arrest in a public place is constitutional as long as there is probable cause to believe the suspect committed a felony.

What does 'source validation' mean in the context of human intelligence (HUMINT)?

Answer: Assessing the reliability and credibility of information provided by a human source

Source validation evaluates both the source's access to the information and their track record of accuracy to determine how much weight to give their reporting.

'Confirmation bias' is a significant risk during pre-interview suspect assessment because it can cause investigators to:

Answer: Selectively interpret ambiguous behaviors as deceptive when they already suspect guilt

Confirmation bias leads investigators to seek evidence that confirms their existing suspicion while discounting contradictory information, threatening investigative objectivity.

An agent finds cartridge cases at a shooting scene. Which area of the cartridge case is MOST useful for comparing firing pin impressions to a suspected firearm?

Answer: Primer face

The primer face receives the direct impression of the firing pin, making it the primary surface for microscopic comparison to the suspected firearm's firing pin.

What is the purpose of a 'speed rock' technique when an adversary is at contact distance?

Answer: To create distance by rocking back while drawing and firing at close range

The speed rock creates a slight rearward lean to move the muzzle away from a grappling adversary while allowing a draw and shot at near-contact distance.

An agent discovers a handgun submerged in a pond. What is the correct initial handling procedure?

Answer: Package the firearm with water in a sealed container to preserve evidence

Submerged firearms should be kept wet in their recovered state to preserve fingerprints and DNA that would be destroyed by drying.

In a questioned document examination, an examiner is asked to determine if two signatures were written by the same person. Which class of handwriting characteristic is examined FIRST?

Answer: Class characteristics such as letter forms and proportions

Class characteristics, including general letter forms, spacing, and proportions, are assessed first to determine if signatures belong to the same broad writing system before examining individual characteristics.

How long after a shooting incident is GSR typically detectable on an unwashed shooter's hands?

Answer: Up to 4–6 hours

GSR is typically detectable on unwashed hands for approximately 4–6 hours, after which normal activity causes significant particle loss.

In mobile surveillance, the 'box technique' is used to:

Answer: Surround a moving subject with vehicles on all sides to maintain coverage

The box technique positions surveillance vehicles ahead, behind, and on parallel streets to maintain contact regardless of turns the subject makes.

FBI agents are required to report any discharge of their weapon (outside of approved training). The report must be filed:

Answer: Within 24 hours or as soon as practical, to the supervisory special agent

FBI policy requires agents to notify their supervisory special agent and submit an official report as soon as practicable, typically within 24 hours, following any non-training discharge.

What is the primary purpose of hollow point ammunition in law enforcement use?

Answer: To expand upon impact and limit overpenetration

Hollow point bullets are designed to expand upon contact with soft tissue, creating a larger wound channel while reducing overpenetration risk to bystanders.

When providing cover for a partner who is moving to a new position, what is the covering agent's primary responsibility?

Answer: Maintain observation and fire superiority on the threat to suppress movement toward the partner

The covering agent must watch the threat and be prepared to engage to prevent the threat from targeting the moving partner.

When an FBI agent uses force and the subject is injured, the agent must NOT:

Answer: Move the subject's body to conceal evidence of the encounter

Moving a body to conceal evidence constitutes obstruction of justice and violates both FBI policy and federal law.

What is the primary purpose of rifling in a gun barrel?

Answer: To impart spin on the bullet for gyroscopic stability and improved accuracy

Rifling consists of helical grooves machined into the bore that spin the bullet as it travels down the barrel, providing gyroscopic stability and dramatically improving long-range accuracy.

Heat exhaustion during an outdoor FBI fitness evaluation is MOST likely to first present with which symptom?

Answer: Heavy sweating, cool and pale skin, and dizziness

Heat exhaustion typically presents with profuse sweating, pale cool skin, and dizziness — distinguishing it from the more dangerous heat stroke.

What is a 'stoppage' in FBI firearms terminology?

Answer: Any unintended interruption in the cycle of operation requiring immediate action

A stoppage is any unintended interruption in the weapon's cycle of operation, requiring the shooter to perform immediate or remedial action to resume firing.
