Excessive force cases often turn on details that disappear fast: a fading bruise, overwritten video, a missing witness name, a confusing social media post, or a timeline that no longer lines up. In general terms, these claims are commonly brought under 42 U.S.C. § 1983, the federal civil-rights statute that allows people to seek relief when someone acting under color of state law violates constitutional rights. For arrests, stops, and other seizures, courts usually analyze force under the Fourth Amendment’s objective reasonableness standard described in Graham v. Connor. For pretrial detainees in jail settings, the Supreme Court has also applied an objective framework in Kingsley v. Hendrickson.
That legal standard sounds straightforward. Proving it in real life is rarely simple.
A recent Bureau of Justice Statistics report on contacts between police and the public, published in October 2024, shows just how many people interact with law enforcement each year. The FBI’s National Use-of-Force Data Collection update released in August 2025 also shows that national data is still incomplete because reporting coverage remained below the FBI’s 80% threshold for incident counts. That gap is part of why individual documentation matters so much in civil-rights litigation.
If you want a broader foundation before diving into the mistakes, it may help to start with a plain-English overview of how excessive force law works, how “objective reasonableness” is applied, and why injury proof matters.

Unlike some legal disputes, excessive force claims are often decided through competing narratives. One side says the force was necessary. The other says it was too much for the circumstances. Under Graham, courts commonly look at factors like the severity of the suspected offense, whether someone posed an immediate threat, and whether the person was actively resisting or trying to flee. The analysis focuses on what a reasonable officer would have done under the circumstances, not on hindsight or personal feelings about police conduct. Graham v. Connor
That often means a case rises or falls on evidence showing what happened, when it happened, who saw it, how much force was used, what injuries followed, and what records exist. Some people assume obvious unfairness is enough. In practice, missing records and inconsistent details can make a legitimate claim far harder to prove.
Below are eight common mistakes that can make these cases more difficult.
One of the most common problems is delay. Bruises change color. Swelling goes down. Cuts heal. Pain that felt overwhelming on day one can look less serious on day ten. When injuries are not photographed or medically documented early, the defense may argue they were minor, unrelated, or caused somewhere else.
This does not mean visible injuries are required in every case. The legal question is still whether the force was objectively unreasonable. But injury evidence often helps juries and judges understand the amount of force involved and whether the official explanation fits the physical aftermath. That is one reason Department of Justice materials in use-of-force oversight matters repeatedly emphasize prompt medical assessment, injury recording, and photographs. See, for example, DOJ settlement and findings materials discussing medical review and documentation of injuries after force incidents, including this Civil Rights Division settlement language and this DOJ findings discussion about force-reporting gaps.
Some people in similar situations try to “wait and see” whether they feel better. From an evidence standpoint, that can create avoidable ambiguity. If you want more detail on the evidence itself, our companion discussion on what tends to carry the most weight in these claims would fit naturally here.
Body-camera footage, dash-camera footage, surveillance video, jail video, business security footage, cellphone clips, dispatch audio, and CAD logs can all matter. The problem is that some systems overwrite data after a retention period. Private businesses may delete footage quickly. Neighbors may save over doorbell recordings without realizing the clip mattered.
Federal civil procedure recognizes the consequences of lost electronically stored information. Rule 37(e) addresses situations where electronically stored information that should have been preserved is lost because a party failed to take reasonable steps to preserve it. Rule 34 also treats electronically stored information as discoverable material. In other words, digital evidence is not a side issue in modern litigation; it is often central.
DOJ policy materials also reflect how significant recordings can be. The Department of Justice has described body-worn camera recordings as federal records in certain federal contexts and has issued policy guidance on preservation and transfer of recorded content. See the DOJ Justice Manual’s discussion of body-worn camera recordings and preservation, along with DOJ announcements on body-worn cameras for federal task forces and federal agents’ camera use.
A person who assumes “the police already have the video” may later learn the key footage is gone, incomplete, or never activated.
