With the appearance of black life that pulls racial injustice and police brutality into sharp focus under appalling circumstances, similar cases of excessive force from the past are scrutinized again.
One such case is that of Tony Temba, a 32-year-old man who died in August 2016 when he was tied up by the police in a parking lot in Dallas.
Tampa was not black, but his case was related to the George Floyd case, the ongoing black life demonstrations taking place around the world, or at least the events that motivated them.
It's all about the phrase "excited delirium".
Here's everything you need to know:
Who was George Floyd?
The death of George Floyd - and the subsequent protests that shook America - caused a sensation around the world, and again draws attention to the massive systemic racial grievances within
On May 25, Floyd's hands - an African American man - were handcuffed lying on his face in a city street while Minneapolis American police officer Derek Chauven knelt on the right side of his neck.
The Chauvin knee remained there for 8 minutes 46 seconds, despite Floyd's repeated pleas "I can't breathe" - 2 minutes and 53 seconds from that time occurred after Floyd became unresponsive. He died in custody.
The repercussions of these events were the most outrageous racially far-reaching, with exciting clashes between demonstrators and police forces across several American cities during the past week.
As racial injustice once again reveals its ugly head, demonstrations have been seen in countries around the world, although most parts of the planet are still under some form of closure due to the Coronavirus.
What will happen to the relevant officers?
Prosecutors have charged a former officer at the George Floyd Center case, and for the first time they have charged three other officers.
Derek Schofen, who can be seen kneeling on George Floyd's neck for more than eight minutes, has been charged with murder for the third degree to the second degree murder.
The three former officers involved in the arrest and murder of George Floyd were also charged with aiding and abetting second-degree murder and second-degree manslaughter.
“There is a high possibility that one or more officers [in the George Floyd case] will confirm the enthusiastic delirium as a defense,” Jeff Henley, a Dallas attorney representing the family of a man who died in Minneapolis at the hands of the police in 2016, said the publication of the criminal justice Marshall Project.
In the last moments of George Floyd's life, as he lay on his face with the knee of a Minneapolis police officer Derek Chauvin on his neck, another officer at the scene asked whether they should push Floyd to his side.
"I am concerned about excited delirium or whatever," he reportedly told Chauvin.
What is "excited delirium"?
Excited delirium is a controversial diagnosis, and is often used when people die in police custody.
Whether it already exists is discussed among experts and police forces alike, but people with zeal delirium are said to be aggressive and unconnected, with a "superpower" imbued with their stimulant drug use like cocaine.
Critics have termed it a bogus science, an appropriate excuse used to justify the excessive police force
Critics argue that it is not a legitimate cause of death, as the police use it as an excuse when arrests involve avoidable deaths, and say the term is disproportionately cited in cases where black and Hispanic men die in custody.
Could "Rave Excitement" clear Derek Chauvin?
Two autopsies were performed on George Floyd, one by the Hinpin County Medical Examiner, and an independent autopsy who ruled Floyd's death as a result of obstructive breathing.
None of the report mentioned the excited delirium.
But how long can it take for Derek Schofen and his partners to go to trial?
"To be accurate, it will take months, and I don't know how many," said Keith Ellison, Minnesota Attorney General.
"It is better to make sure that we have a solid case, which has been fully investigated, and examined, before we go to trial, rather than rushing it in. It will take some time and I cannot set a deadline for that."
Who was Tony Timpa?
In August 2016, Temba called 911 to say he went out of his medication to treat schizophrenia and depression and needed help.
In the camera video obtained by Dallas Morning News, Temba was fixed to the ground in a flat post with a knee on his back while pleading with the police to release him.
"You will kill me!" He shouted again and again.
Three officers laughed and laughed while holding Temba on the ground for 14 minutes. When he became unresponsive to his face in the grass, the officers joked that he had slept.
"Back to school! Come on, wake up!" One of the officers said, while another jokingly said: "I don't want to go to school! Five more minutes, mom!"
"The footage graphically depicts the death of an unarmed young man," family lawyer Jeff Henley told the New York Times.
In the case of Temba, one of the officers asked if he should turn him over to his side; A medical examiner concluded that Temba's death was caused by a combination of cocaine and physical stress, “sometimes referred to as erotic delirium syndrome.”
