Forty Seconds After the Cuffs
At 00:50 a patrol team responds to a fight outside a bar. The suspect, F, 24, is drunk, shouting and refusing to sit down; he is unarmed and two officers are present. During handcuffing he twists his arm. Sergeant G, 38, with twelve years' service, takes him to the ground and presses a knee into F's upper back for about forty seconds after the cuffs are on and after F has stopped moving and says he cannot breathe. Officer H, 23, who is on probation, is wearing a body camera that recorded the whole sequence. F is later found to have two bruised ribs and a small abrasion.
At 01:30 G tells H: 'Footage like that gets lost. Don't put the knee part in your report, it just complicates things for both of us. Your evaluation is next month.' At 09:00 a relative of F comes to the station and leaves an envelope for H containing KRW 300,000 in cash and a note asking for 'a good report.'
1. Was G's use of force lawful? Apply the governing standards and identify the precise moment at which the justification changes.
Read the worked answer
Force used in the execution of duty must be necessary to achieve a lawful purpose and must be proportionate to the circumstances; it must stop when the need for it stops.
Up to the handcuffs the force is defensible. F was drunk, shouting, refusing instructions and twisting his arm during handcuffing; two officers were present but he was actively resisting. Taking a resisting arrestee to the ground to complete the handcuffing is a recognised control technique and is proportionate to the resistance.
After the handcuffs the analysis changes completely. At the moment the cuffs were secured, F was restrained, prone and not moving. The legitimate objective, control of a resisting person, had been achieved. A knee driven into the upper back of a prone, handcuffed person for forty seconds serves no purpose except pain compliance, and carries a recognised risk of positional asphyxia; 'I cannot breathe' is exactly the warning sign that requires immediate release of pressure and repositioning. The bruised ribs confirm that the pressure was substantial, not incidental contact.
The injury converts this from a question of excessive technique into potential criminal liability for injury, a civil liability claim against the state, and a disciplinary matter. It also triggers a duty of care: once the person is restrained and complaining of breathing difficulty, officers must place him on his side or upright, monitor him, and summon medical help if needed.
What the report must show: the time the cuffs were secured, when F stopped resisting, when he said he could not breathe, and how long pressure continued after each of those points. Those times decide the case.
2. What are H's obligations regarding the body-camera footage and the report? Can the footage be deleted, and what protection does H have if he reports G?
Read the worked answer
The footage. Recordings of enforcement action are official records. They may not be edited, deleted, overwritten or withheld, and there is a minimum retention period (commonly thirty days) during which footage of an enforcement incident must be preserved unless it is formally retained for an investigation or complaint. Here, the recording is evidence of a possible criminal offence by an officer, so H must take positive steps to preserve the original: export it unedited, record the hash or file identifier, and log the export. Deleting it, or allowing it to be deleted through inaction, is destruction of evidence and can itself be an offence, and it would convert H from a witness into a participant.
The report. H must write what he saw, including the forty seconds, the complaint of breathing difficulty and the timing. Omitting it is not discretion; it is a false official record, and the fact that a senior officer asked for the omission does not transfer responsibility. H should submit his own account, keep a copy, and if G refuses to accept it, report through the chain above G or directly to the inspection or audit unit.
Protection. Whistleblower and public-interest reporting protections apply to a public official who reports misconduct within the organisation, and retaliation by way of an adverse evaluation is itself a disciplinary matter. H should also record the evaluation threat, with date and words, in a contemporaneous note.
Do not confront G alone and do not hand over the only copy of the footage.
3. Analyse the envelope and the evaluation pressure together. What should H do in the next twenty-four hours, and why?
Read the worked answer
The envelope. Cash given to a public official by a person connected with his duties is not a courtesy. Accepting money in connection with official business can constitute bribery, and even where the corrupt agreement is arguable, the conduct code governing police officers prohibits receiving money, gifts or entertainment from anyone with an interest in an official matter. The note asking for 'a good report' supplies the purpose expressly, so there is no room for a claim of innocent receipt. Retaining the money while saying nothing converts an offer into a completed acceptance.
The interaction with the evaluation threat. G is pressing H to falsify a record and is using probation and an upcoming evaluation as leverage. Together with the envelope, H is being pushed into two separate offences at once. Silence is the worst option: it exposes H to the bribery allegation, to a charge of falsifying official documents, and to being treated as G's accomplice.
What to do within twenty-four hours.
- Refuse the envelope in the presence of a witness, or if that is impossible, register it immediately as received official property and do not open or spend the cash; record who left it, when, and what the note said.
- Report both the envelope and G's instruction to a supervisor above G, and to the inspection unit in writing.
- Preserve the body-camera original before anything else.
- Write H's own report, factually and without speculation about G's motives.
Why now. Delay weakens every account H will give and hands the initiative to whoever reports first. The probation status is a reason to report, not a reason to stay quiet: the duty to obey lawful orders does not extend to orders to destroy evidence or to accept money.
