The Box Cutter in the Grocery Lot: Taser Distance, Deadly Force, and a Partner's Kick

The deployment as planned is a bad idea, and you should say so out loud.

The Taser is a close-range, single-shot tool. Its maximum deployment range exists because probe spread and accuracy degrade with distance - the two probes must land far enough apart to complete a circuit through enough muscle mass. At 28 feet you are past the manufacturer's rated maximum, the man is moving, and Officer B has never deployed one under stress. A miss leaves a knife-armed, agitated man 28 feet away with your only less-lethal option spent and shoppers behind him who could be struck by a stray probe.

Environment and background: fifteen to twenty civilians moving between cars are directly behind the target. Any projectile, probe, or round that misses goes into that crowd. That is a decisive factor.

Other options are worse at this range: OC is effective at roughly 10–12 feet, not 28; a baton against an edged weapon is a losing proposition no matter how good the officer is.

What you direct:

• Use the vehicles as cover and keep 25 or more feet, moving laterally, not backing blindly.
• Assign roles: one officer communicates, one has a lethal option at low-ready in case the man closes on the clerk.
• Give clear, simple commands - "Drop the knife, I don't want to hurt you" - and give time.
• Position between the man and the store entrance; ask dispatch to have the clerk lock the doors and move back.
• If a Taser is used, it should be inside the effective range, with lethal cover designated and a plan for what happens when the five-second cycle ends.

Legal note: a poor tactical choice is not automatically an unconstitutional use of force - Graham judges the moment, not hindsight - but pre-force decisions feed the totality analysis, and juries notice. The strongest position is one where you can explain why every option you chose was reasonable at the time.

Standard. Under Graham v. Connor, force is judged by objective reasonableness from the perspective of a reasonable officer on scene. Under Tennessee v. Garner and Missouri's officer-use-of-force statute, deadly force is justified only when the officer has probable cause to believe the person poses a significant threat of death or serious physical injury to the officer or others, and a warning must be given where feasible.

Facts that support deadly force:

• An edged weapon, blade extended, at 8 feet from an unarmed civilian. The reactionary gap matters - a determined attacker can cover 21 feet in about 1.5 seconds; 8 feet is inside the time it takes to draw and fire.
• The clerk is cornered in a doorway with no clear retreat.
• The man's stated intent - "I'm not going back" - combined with movement toward a person, not away.

Facts that cut the other way:

• No verbal threat to the clerk.
• The blade was being used on himself minutes earlier, so self-harm may still be his intent.
• The clerk may be able to retreat inside and lock the door.

Decision: if he advances on the clerk or turns toward an officer with the blade raised and continues closing, deadly force is justified. Give a loud, specific warning if it can be done without losing the ability to act - "Drop the knife or I will shoot." Do not attempt to shoot the knife or wound him in the hand; that is not a viable tactic and endangers bystanders.

Document: exact words, distances in feet at each decision point, time elapsed, backdrop, bystander positions, the number of rounds fired, and what changed in his behavior immediately before you fired. Vague references to "he was threatening" will not survive review.

First 60 seconds:

• Order Officer B to stop and physically put yourself between him and the subject.
• Take control of the subject, keep him secured, and request EMS for the rib injury. Do not leave him unattended and do not let a partner "check him out" alone.
• Check your own body camera is recording; note Officer B's camera status.

Next hour:

• Notify a supervisor immediately, and request that the responding supervisor not be someone who worked with Officer B that night.
• Preserve all body-worn camera footage before any retention window lapses, and document that you did so.
• Write your report factually, including the kick, the words, and the time. Your report is evidence; leaving it out is itself misconduct and makes you a defendant instead of a witness.
• Photograph the subject's ribs and any marks, and get the medical evaluation documented.

Legal exposure: an officer who sees excessive force and has a realistic opportunity to intervene but does nothing can be liable under 42 U.S.C. § 1983, and the agency can be liable for a failure-to-supervise or code-of-silence theory. A kick to a handcuffed, restrained person has no legitimate purpose - it is not a control technique.

Disclosure: the prosecutor must be told. This is potential Brady/Giglio material, and it will affect every case Officer B touches. POST licensing discipline for excessive force and for failure to report can include suspension or revocation.

The loyalty trap: Officer B's conduct created this situation, not your report. Silence does not protect your partner - it makes you a co-participant with a credibility problem you cannot fix.
