The former head of training for the Minneapolis Police Department, Inspector Katie Blackwell, has testified that former Officers J. Alexander Kueng, Thomas Lane and Tou Thao acted in a way that was “inconsistent” with department policies. Blackwell, who testified Monday for her third day, said the trio defied MPD training by failing to intervene to stop Chauvin, not rolling Floyd onto his side when he stopped resisting, and not providing medical aid when he stopped breathing and they couldn’t find a pulse.

Federal prosecutors say Kueng, Lane and Thao violated their training by failing to act to save Floyd’s life on May 25, 2020, when fellow Officer Derek Chauvin kneeled on the Black man’s neck for 9 and a half minutes while Floyd was handcuffed face down and struggling to breathe. Kueng allegedly kneeled on Floyd’s back, Lane held his legs and Thao kept bystanders back.

Thao’s attorney, Robert Paule, on Monday challenged Blackwell on whether the officers received adequate training, including on the use of neck restraints. He also presented the department’s training materials on how to recognize and stop someone experiencing “excited delirium” — an agitated state that the training materials say could warrant a more forceful restraint.
