But there was no danger to warrant lethal force...
This is something that U.S police aren't conditioned to. Lethal force is very specific and a unique situation, crime in almost all European countries is stopped without any lethal force, just good tactics and training. Europe isn't any different with the types of crime, it's all the same, police don't use lethal force.
Why does lethal force need to be used here? Are police officers so badly trained that they cannot deal with someone throwing rocks? U.S police has the best equipment in the world for police (and some questionable), but they seem to lack the training to deal with situations that don't require lethal force. So tazing isn't working so they decide "well, better just kill him?"
European police deal with murderers on the loose with guns and they still catch them without lethal force. If so many police forces can do it, why can't the U.S? He had fucking rocks. Rocks. Let that sink in. Police officers can't deal with that? If lethal force is the only strategy to use to diffuse a situation then there's a problem with the training of officers. Lethal force is NOT the standard in many countries and they deal with the same situations.
Rocks.
