The U.S. Supreme Court has said an officer's fear for their life in the heat of the moment matters, even if in hindsight it turns out they weren't in danger. Chief Justice William Rehnquist wrote in a 1989 ruling that shaped the legal landscape that the “calculus must embody an allowance for the fact that police officers are often forced to make split-second decisions about the amount of force necessary in a particular situation."
It takes the brain about three-fourths of a second to react to a perceived threat, said Chris Burbank, a former police chief in Salt Lake City who is now with the Center for Policing Equity. Most police can then draw a gun and fire two accurate rounds in 1.5 seconds, so the pivotal portion of a confrontation can be over in less than three seconds.

The often-used
“show me your hands!” command can unintentionally accelerate a confrontation. The motions of a person trying to obey can appear at first like the moves someone makes to start an attack, said Von Kliem, a former police officer and director of consulting division for the Force Science Institute. Some in law enforcement-training circles have had concerns about how the phrase affects a situation since the mid-1990s, though it's still often used without causing serious problems.

Journalists are responsible for creating the first draft of history, quickly. To do this, the profession has routines and norms that help it produce news in a systematic way. Breaking news reporters often rely on the accounts and statements made by official sources. This often includes the narratives and statements put forward by official sources – politicians, police and official spokespeople. These are people journalists may work with regularly; they are often more accessible under the pressure of a deadline – especially if a victim’s friends and family are hard to reach or less willing to speak to the press. And even if officials are wrong or say something defamatory, a journalist can often report what they say with legal impunity. All of this gives police an opportunity to shape the initial version of the event – and it gets their version of the story into the public consciousness before victims, families and their supporters are able to. But often they do so in a way that is incomplete, misleading or presented for strategic reasons. Official statements may, intentionally or not, withhold or omit information. In Toledo’s case, the original statement given to media on the day of the shooting mentioned that “one armed offender,” a “male,” fled from police and a “confrontation” took place. “The officer fired his weapon striking the offender in the chest.” There is no mention that, as later emerged, it appears that the gun was tossed and Toledo was raising his hands. The incident report listed Toledo as a “John Doe” and between the ages of 18 and 25 – and thus failed to reveal that Toledo was a child.
