Soon after it was disclosed to the public that charges would not be brought against the two Sacramento police officers, a wanted poster targeting the two officers was circulated by those who were upset with the D.A.'s decision.  The poster includes the officers' names and pictures, their "gang affiliation" (Sacramento P.D.), and announces that these two officers "should be considered armed and dangerous."  To make matters worse, UC Davis English Professor, Joshua Clover, has openly advocated for the death of all police officers, even posting on Twitter that "it's easier to shoot cops when their backs are turned." 

California Assemblywoman Shirley Weber (D-San Diego) recently introduced AB 392 in effort to change California's legal standard for police use of deadly force.  She, along with California Governor Gavin Newsom and Sacramento Mayor Darrell Steinberg, support making police shootings harder to "justify."  Dan Walters of Calmatters had this to say about California's current use of force law and the Clark shooting:

Had a civilian done what those two [Sacramento] officers did - fired multiple rounds blindly at an indistinct figure in a backyard - he or she would almost certainly be prosecuted, at least for manslaughter if not for murder.

Knowing your target, firing only to protect oneself or another from death or great bodily harm and using minimum force to end the threat are drummed into civilian gun owners during firearms training.

There is a difference between a civilian using a gun to protect him or herself or another, and a police officer who is in active pursuit of a fleeing subject, who is hopping fences in a residential neighborhood, in the dark amidst reports that the subject has been smashing out car windows and the back sliding glass door of an 89-year old man's house.  A friend of mine is a police officer in a bay area city that has a very high overall crime rate.  One night he found himself in a similar situation as the two Sacramento officers.  He was chasing a man over residential backyard fences in the middle of the night. It was pitch dark.  As he hopped a fence, he came into direct contact with the subject and had a gun pointed at his head.  The subject pulled the trigger without hesitation.  The gun did not fire because the gun was out of bullets.  Had a bullet been in the chamber, my friend would have died leaving a wife and three boys under the age of 10. This is what police officers face daily all over the United States. 

Unbeknownst to the Sacramento officers at the time, on the night of Clark's death, he was under the influence of alcohol, Xanax, codeine, hydrocodone, marijuana, and cocaine metabolite.  The two police officers demanded that Clark show his hands numerous times.  He refused.  Clark continued to ascend towards the officers in a dark back yard despite warnings to stop.  The officers then saw a flash of light come from Clark's hands.  The officers literally had seconds to decide what to do.  In that moment, those two officers could have easily joined the list of those 62 fallen police officers.  There is no doubt that the "officers believed they were in danger when they shot and killed Clark" and the decision not to pursue charges against them is to be lauded.
