On Friday, jurors sided with Mr Yanez's version of events, acquitting him of one count of second degree manslaughter and two counts of intentional discharge of firearm that endangers safety.
In a blurry black-and-white video taken of Diamond Reynolds and her 4-year-old daughter as they sit in the back of a squad vehicle shortly after the fatal shooting of Philando Castile, the young girl hugs her mom and pleads with her not to yell or try and take off her handcuffs.
Recently-released documents from Jeronimo Yanez's trial for the murder of Philando Castile have revealed that Yanez's reasoning for shooting Castile stemmed from the smell of marijuana coming from the latter's auto. He asks Castile for his license and insurance.
"I can keep you safe", the girl says.
YANEZ: OK, don't reach for it then. The shooting of the innocent motorist happened in front of his girlfriend and her four year old daughter who were occupants of the auto. In his wallet, Castile also had a gun permit. Unfortunately, this inept police officer's completely unfounded fear for his life was considered enough of a reason to acquit him of any wrongdoing and that fear stemmed partly from the smell of "burnt" marijuana.
Police were dispatched to Lyles' house after she called to report the burglary. "And then I see a front seat passenger, adult female in the front seat".
The squad-car video was shown in court but not released publicly until Tuesday. Suddenly, the situation escalated when the officers saw Lyles clutching a knife. What officer Yanez told police officers investigating the shooting shows just how poor the judgment, and the ignorance, of the young officer was.
Her interactions with her daughter were captured on a camera inside the squad auto after they were escorted inside it at the scene. Within seconds, at least five shots were fired. I don't believe questioning this verdict or criticizing Officer Yanez is, as some would claim, an indictment or sweeping criticism of all police officers. Both officers have been placed on paid administrative leave. She tells the officers she feels like a prisoner. The man was gone when officers arrived, but they allegedly found Lyles holding a pair of large scissors which she refused to drop. Sunday's audio includes a discussion between the two officers about this previous incident. He - four years as a police man, he was very honest. The officer seemed to panic, and made a rash decision. He was sacked from the police department immediately after.
"You just killed my boyfriend", Reynolds says just before she begins to live-stream the resulting chaos on Facebook, allowing the world to watch Castile die from his wounds in real-time.
This isn't the first time a police officer has cited the alleged danger posed by pot to justify a confrontation that turned deadly.
She sobbed and continued begging her mother to calm down.
And if smoking in front of children makes one a cold-blooded killer, well, then we here at Blavity have seen hundreds of killers roaming free on the streets.
