Police: NO KNOCK RAID: A homeowner shoots and kills a police man and no Drugs are found. Should the person be charged?

The home owner was standing his ground.

The careless use of SWAT teams in no-knock drug raids -- when heavily armed police burst into a home without warning -- has resulted in a long list of innocent people being killed or seriously injured in the United States. 2014 alone found SWAT teams in Georgia senselessly killing businessman David Hooks and maiming toddler Bounkham “Baby Boo Boo” Phonesavanh. And when those raids victimize people who aren’t even selling drugs, narcotics officers seldom face criminal charges and are given every benefit of the doubt. But if, on the other hand, Americans shoot narcotics officers during militarized drug raids—perhaps believing that they are being robbed and are acting in self-defense—charges of first-degree murder are likely. 
The case of Marvin Louis Guy in Texas is a glaring example.
Guy, an African-American man who is now 50, was the target of a no-knock drug raid on May 9, 2014. Narcotics officers, operating on a tip from an informant who claimed that Guy was selling bags of cocaine, carried out a SWAT raid on his home in Killeen, Texas at around 5:30 AM—and Guy grabbed his gun and opened fire. Charles Dinwiddie, one of the officers, was hit and died two days later. Guy was charged with capitol murder, and prosecutors are seeking the death penalty despite his assertions that he thought he was acting in self-defense. Guy’s trial is scheduled for June of this year.
