“I Can't Breathe” on the Grocery Store Tile
18:12 at a Surrey grocery store. Working loss prevention, you watch a male in his early twenties put four items worth about $180 into a backpack, walk past the last point of sale without paying, and head for the exit. You identify yourself at the door and tell him he is being detained for police. He shoves past you. You take his upper arm; he swings, you both go down, and he ends up face-down on tile. Your partner kneels across his upper back. The male says “I can't breathe” twice, then stops speaking. He is large and he smells of alcohol. About fifteen people are filming. Police are four minutes out. The store manager tells you to “just let him go, it's not worth it.”
1. Was the detention lawful? Explain your basis, and state how the analysis changes if he had already been 40 metres down the sidewalk when you caught up to him.

At the door: defensible. Forty metres down the sidewalk: much weaker.
Basis for the arrest at the door:
- A private person may arrest without warrant a person found committing an indictable offence, and a property owner or their agent has an additional power in relation to property and theft. Theft of merchandise is a criminal offence; I observed the whole sequence and I am acting on the occupier's behalf.
- The arrest must be announced (I did identify myself and say he was detained for police), I must deliver him to police promptly, and I must use only as much force as is reasonable in the circumstances - a person acting on lawful authority is protected for reasonable force but criminally exposed for excessive force.
The 40-metre variation matters because:
- The power to arrest is tied to finding him committing the offence, not to investigating one that is over. Once he is out the door and away, the basis shifts toward belief that he committed an offence and that he is escaping from someone with lawful authority who is in fresh pursuit - a harder test that depends on continuity of pursuit.
- The further away and the later it is, the more the lawfulness rests on well-documented, continuous, reasonable-grounds pursuit and on the offence being one that supports it.
Wrong turn to avoid: treating “he took $180” as a permanent licence to chase him for three blocks. The value, the risk to the public, and the strength of identification all factor into whether a detention is proportionate, and a bad detention destroys the case and exposes me.
2. Assess the force used, up to and including the restraint. Identify the specific risk and state what you do in the next sixty seconds.

The takedown is defensible; the position he is in is a medical emergency.
Force analysis:
- The initial physical control was a response to a shove and an attempt to leave - a proportionate, reactive escalation, not a pre-emptive strike.
- A knee across the upper back of a prone, large, intoxicated male is the highest-risk element in this entire scenario and the one most likely to be judged unreasonable in hindsight, regardless of intent. Prone restraint with weight on the back restricts the mechanics of breathing and is associated with sudden death, particularly with exertion, alcohol, obesity and agitation. “I can't breathe” followed by silence is not defiance - it is a red flag for a deteriorating airway.
Next sixty seconds - in this order:
- Get the weight off his back. Partner off, now. Move him to a recovery/side-lying position, or at minimum seated upright.
- Talk to him and check responsiveness - voice, then a shoulder shake, then breathing and pulse. If unresponsive or not breathing normally, start CPR and call EHS immediately.
- Call EHS yourself rather than waiting for police, and say exactly what happened: prone restraint, complaint of inability to breathe, loss of responsiveness, duration.
- Keep hands on him only as needed to prevent escape - if he is unresponsive, medical care outranks custody. Handcuffs, if applied, go to double-locked and checked.
- Ask the manager to move the crowd back and preserve the scene; do not delete or comment on anyone's video.
The manager's “just let him go” does not override a medical emergency. If he is unresponsive, custody is moot; if he recovers and police arrive, they take him.
3. What must you report, and what will a reviewer look for?
Read the worked answer
Report immediately, in writing, before the details blur - not at 06:50 from memory.
Obligations:
- Notify the duty manager/supervisor immediately on any use of force involving a takedown, a restraint, a complaint of breathing difficulty, or any injury - most company policies make this a phone call, not a note at end of shift.
- Complete a use-of-force report within the policy deadline, with the arrest report, witness statements and a request to preserve CCTV.
- Report the EHS attendance and outcome, and any injury to the subject or to staff.
What a reviewer (police, a civil litigator, a licensing regulator, my own insurer) will actually look for:
- A time-stamped narrative of each action and each reaction, with the subject's words quoted, including “I can't breathe.”
- Duration of the prone restraint - the single most damaging blank in most reports. If the answer is “about three minutes,” write three minutes.
- What I did when he stopped speaking, and how fast.
- De-escalation attempted: what I said, what the manager said, whether I considered waiting for police instead of taking him at the door.
- Proportionality against the loss: $180 of merchandise against a restrained airway is the comparison a plaintiff's lawyer will put to a jury.
- Consistency across reports. Fifteen people were filming; the store's own cameras cover the exit. Any gap between my report and the footage becomes the story.
- No conclusions in place of observations. “Minimal force used” is a conclusion; “I placed my left knee across his upper back for approximately 40 seconds” is a fact. Write facts.
