"While the department had received court approval for a “no-knock” entry, the orders were changed before the raid to “knock and announce”, meaning that the police had to identify themselves."
Additionally, KY AG Cameron stated that the credible eyewitness had testified that LMPD announced themselves.
In Kentucky, once police announce, you do not have safe harbor under Stand Your Ground. In fact, after Walker fired, the only SYG belonged to Officer Mattingly. As it turns out, Officer Cosgrove fired the fatal shot; Officer Hankison missed St. Bre altogether.
The prosecutors would have to prove that the occupants could hear the announcement to erase SYG protection. No cams, no audio, didn’t use a bullhorn, so no evidence that the announcement was audible enough to be heard from inside.
That’s wny Walker is not being prosecuted.
