What kind of fuckery is this in the Chauvin trial?

the prosecutors 'find at the last minute' a test result, and wait for 8AM in the morning of the day the defense rests, when their expert witness is gone out of the state, and decide to recall a previous witness to narrate nonsense at the last minute

they leave Nelson with no time to even contact his expert witness, who is on a plane

FUCKERY, UP UNTIL THE LAST MINUTE…
