It turns that cops and medical examiners are conspiring to use Sickle Cell Trait to excuse police misconduct.

Sickle Cell Trait is the heterozygous form of Sickle Cell Anemia, and it has a limited effect on people.  It is almost universally asymptomatic.

Nevertheless, because it is almost exclusively associated with Black people, cops and their enablers use it as an an excuse for beating people to death:

When they carried the body of a 32-year-old Black man named Lamont Perry out of the woods in Wadesboro, N.C., there were no protests over his sudden death in police custody.

No reporters camped at the scene. No lawyers filed suit.

Instead, the final mark in the ledger of Mr. Perry’s life was made by a state medical examiner who attributed his death in large part to sickle cell trait, a genetic characteristic that overwhelmingly occurs in Black people. The official word was that he had died by accident.

But the examiner’s determination belied certain facts about that night in October 2016, public records and interviews show. Accused of violating probation in a misdemeanor assault case, Mr. Perry was chased by parole and local police officers through the dark into a stand of trees, where only they could witness what happened next.

He had swelling of the brain, and a forensic investigator reported that he had an open fracture of his right leg. He was covered in dirt, and residents of a nearby housing complex told his family that when the officers emerged from the woods, their shoes and the bottoms of their pants were spattered in blood.

Yes, clearly this is a case of Sickle Cell Trait causing a broken leg, closed head trauma, and massive bleeding.

Mr. Perry’s case underscores how willing some American pathologists have been to rule in-custody deaths of Black people accidents or natural occurrences caused by sickle cell trait, which is carried by one in 13 Black Americans and is almost always benign. Those with the trait have only one of the two genes required for full-blown sickle cell disease, a painful and sometimes life-threatening condition that can deform red blood cells into crescent shapes that stick together and block blood flow.

The New York Times has found at least 46 other instances over the past 25 years in which medical examiners, law enforcement officials or defenders of accused officers pointed to the trait as a cause or major factor in deaths of Black people in custody. Fifteen such deaths have occurred since 2015.

In roughly two-thirds of the cases, the person who died had been forcefully restrained by the authorities, pepper-sprayed or shocked with stun guns. Scattered across 22 states and Puerto Rico, in big cities and small towns, the determinations on sickle cell trait often created enough doubt for officers to avert criminal or civil penalties, The Times found.

“You can’t put the blame on sickle cell trait when there is a knee on the neck or when there is a chokehold or the person is hogtied,” said Dr. Roger A. Mitchell Jr., the former chief medical examiner for the District of Columbia and now chairman of pathology at the Howard University College of Medicine. “You can’t say, ‘Well, he’s fragile.’ No, that becomes a homicide.”

I guess that we need to add, “Living while Black,” to, “Driving while Black,” to the list of offenses that the authorities find worthy of the death penalty.
