I think you are very optimistic about the way the United States and its various instruments handle complaints, respect the law and police themselves.

I am not an optimist. I think most nations are more interested in their material goals than ideological integrity. I also think that model is more consistent with history than the other.

After all - how would a government with such transparency and integrity let its armed forces fire on civilians to begin with?
