How low can it go in the US?

I was just reading a New York Times article about a black woman fatally shot eight times by a Louisville police officer using a “No-Knock Warrant”. This happened more than three months ago. So far none of the three police involved have been charged over the matter. “The police’s incident report contained multiple errors. It listed Ms. Taylor’s injuries as “none,” even though she had been shot at least eight times, and indicated that police had not forced their way into the apartment — though they used a battering ram to break the door open.

And Trump plumbs new depths with his tweet yesterday after the Supreme Court rejected his plan to toss the “Dreamers” out of the country. Trump said,

"These horrible & politically charged decisions coming out of the Supreme Court are shotgun blasts into the face of people that are proud to call themselves Republicans or Conservatives. We need more Justices or we will lose our 2nd. Amendment & everything else. Vote Trump 2020!" 

This is not a dog whistle; it’s a racist foghorn.
