Wonder what it was that he couldn't plant that evidence inside that house? They probably would have never been caught if he had been able to, like many times before no doubt.
I suspect getting shot in the throat by somebody trying to defend their home and wife against a group of home invading criminals using their police uniforms as a disguise foiled Goinses' plans. Since he reportedly couldn't talk he couldn't even coordinate the lies needed for a cover-up with his fellow criminal policemen.
And now he should be headed to prison for the rest of his life. Some of his associates should be joining him.
