Based on the little that I have seen regarding this case I have the following opinions/observations.

1.  We don't know exactly what happened prior to the suspect being put on the ground and restrained.

2.  The police officer used an incorrect method to restrain the suspect, especially if the suspect was cuffed.  Putting a knee on the throat is a HUGE "no-no".

3.  We don't know the physical/mental health history of the suspect.

4.  From what I understand the suspect was under the influence of some kind of drug and resisted when the police officers were trying to put him in the patrol vehicle.

Based on what I have seen and understand about this case, the officer with the knee on the neck should probably be charged (and convicted) with manslaughter.  A murder charge would never hold up unless there is evidence to prove that he had the intent to kill the suspect (hard to prove based on the evidence known).  He was blatantly wrong and should face the consequences.

Regarding the other officers at the scene, I find it difficult to come up with a crime that they should be charged with.  Should they have perhaps tried to stop the officer with the knee to the neck?  Yes.  However failure to do so is not a crime.  It is/was grounds to get fired, but they did not actively participate in a crime.

Again, this is just my opinion based on the facts that are known.
