CrimeOnline’s Nancy Grace wants to know why a now-former police officer hasn’t been charged with first-degree after a viral video showed the man kneeling into victim George Floyd’s neck, reportedly causing fatal injuries.

Derek Chauvin is behind bars after the fatal incident, charged with third-degree murder and second-degree manslaughter after kneeling on Floyd’s neck for eight minutes while onlookers pleaded with him to stop. Floyd was pronounced dead on the same day and Chauvin was subsequently arrested.

Questions now arise, not only about his charges, but why Chauvin used such aggressive procedures on Floyd, who was being questioned at the time for possibly using counterfeit money to pay for a pack of cigarettes.

“What you’re taught at the academy or any retraining is that once you have the suspect under control, that’s it,” attorney James Shelnutt, who served as a metro Atlanta detective for over 20 years, told Grace. “You’ve got them under control. So as he’s down on the ground with, you know, handcuffed and at that point, if he was still being belligerent, you would simply carry them and place him in the vehicle.”

Oshins added that Chauvin was given a “watered-down murder charge” instead of first-degree murder, which comes with a more severe punishment upon conviction.

“Why is this not murder one?” Grace asked during the latest “Crime Stories,” airing on Fox Nation and Sirius XM.

Shelnutt added that it’s not difficult to get someone under control once they’re handcuffed and on the ground. Surveillance footage showed that Floyd was handcuffed during the incident with three officers holding him down.

“It doesn’t take putting your knee on the back of someone’s neck to maintain control of a man just on the ground. I just can’t fathom under what training scenario or what real-life scenario that that would be appropriate.”

Meanwhile, an independent autopsy requested by Floyd’s family indicated that he passed away from asphyxia due to sustained forceful pressure on his neck and back. Toxicology results are still pending.

“We wait as God willing, justice unfolds, no matter what it takes, no matter what it causes. The truth is what we’re looking for,” Grace said.
