Because the Louisville Metro PD is the personal tool of leftist loon mayor Greg Fisher. Louisville is the liberal mecca in Kentucky. Short of the protestor shooting McConnel, the police there wouldn’t bother to show up.

I don’t know why some Republicans are afraid to use the tools for protection that every single municipality in the country affords them. If you are confounded by obviously biased bureaucrats, document it. Every phone is video camera.
