A lawyer friend informs me:
There was no acquittal in the Breonna Taylor situation: a refusal to charge for murder, yes, but there were charges that are going to trial. Yesterday was the Grand Jury’s charging decision. If it was a no knock warrant, executed lawfully, that may be the correct charging decision. But whether the no knock warrant should have been issued is a different question.
