Judge Andrew Napolitano this afternoon weighed in on the police-involved shooting in South Carolina, remarking that it’s “inconceivable” that the officer in this case could be acquitted of murder.

Video appears to show Michael Thomas Slager shoot at 50-year-old Walter Lamer Scott eight times as Scott fled. The shooting followed a traffic stop over a broken tail light, authorities say.

Napolitano explained that the law gives police discretion to use deadly force when necessary to stop a person from using deadly force himself. But Napolitano noted that Scott apparently had no weapons, was stopped for a broken tail light and was being chased when he was shot, according to the video.

“It’s almost inconceivable that he could be acquitted no matter what preceded the tape,” Napolitano said.

Napolitano explained that Slager was charged with murder for what happened after the shooting. Napolitano said that the video suggests Slager planted his stun gun at the death scene so that he could argue that Scott stole it. Planting evidence is an independent felony, which would indicate consciousness of guilt on the part of the officer, Napolitano said.
