Do Government experiment on its own citizens from time to time?

Sure. There was an experiment during the Cold War where black cancer patients were given very high doses of radiation to see how much radiation the human body could take.

We had a 'bomb scare' late in the afternoon (peak hour) in Sydney Australia a couple of decades ago, where a major railway station was closed to the public. Total chaos followed with people queueing up and taking hours to get home. The popular theory amongst staff was that it was a set up by the state government to create this to 'practice'/see how they would handle this crisis if it really happened . . .  

Happens all the time. The USA did a lot of syphilis experiments that make some of the Nazi experiments look humane.

If it is under the pervue of the CIA, nothing would surprise me. 

I totally agree, we should be abducting people to underground lairs and making them into super soldiers because that would be cool and also help our government to win

YEs the US Government has several times through history
