The Indians at Wounded Knee were not American citizens. (Native Americans were given full citizenship in 1924) This doesn't make Wounded Knee okay, but this example makes no sense.
There is no evidence that the shootings at Kent State were directed by higher government authorities. This again doesn't even remotely excuse what happened, but when you're comparing it to what happened in Egypt recently with government aligned militia being specifically sent to attack protesters it's just not the same thing.
The US government has conducted all sorts of shameful actions against its citizens over the years, things that we should rightly condemn. Sill, the two lunatics here trying to compare the US to North Korea are simply nuts.
I'm a little surprised at how much you defend this abuse, at some point an (R) gets back into the White House and controls all of this.
Regardless of whether the Native Americans had citizenship, the United States had dominion over them and had a responsibility to threat them civil. The United States had a long history of doing the exact opposite.
So we skip them, ok fine. Then we get to the concentration camps for the Japanese-Americans. Or shall we quibble about the white washing of history and call them internment camps?
What about the Tuskegee experiments?

Those went on for 40 years!!! Can we even name a nation that conducted medical experiments on its citizens for longer than the United States?
The experiment lasted four decades, until public health workers leaked the story to the media.
Yup. Snowden is the devil all right. Leakers are the heroes of the United States because this country has a long history of abusing its people and hiding it very well until someone says enough and leaks it to the media.
I'm sure there were people even then defending these experiments as needed just as you defend the government on this issue. You really should reevaluate which side of history you keep siding with.
