I don’t see any way a murder charge holds up in this case. The case is filled with way too many factors that constitute “reasonable doubt” that will weigh heavily against a conviction.
I agree with you. !st degree murder charges will be difficult to prove. Not a lawyer, but my understanding of the charges is that prosecution must prove beyond a reasonable doubt that the police officer planned the murder in advance (premeditation) and that killing the guy was the officers intent.
