Hoping that there is "truth in sentencing" and the two decades sentence stands firm.
The murder was not committed following say, the officer's arrival on a violent crime scene and a complex, rapidly changing situation. Rather, the murder was committed after the officer knew that the victim did not truly pose a deadly threat.
Subjectively, I think the murder had a social cleansing aspect to it. Little voices are telling me that the victim's low socio economic status contributed towards an attitude of: Got the pretense I needed. Permanently solving this recurring problem- now. Subjectivity cant be used at trial. But... this is not a trial.
