Gary McKinnon was obsessed with UFOs and believed governments were covering up evidence that UFOs exist.
In the year 2000, he decided to do a little digging. Gary was a computer expert so what better place to dig than on US government computers?
What he found was so shocking that it sent the entire United States government into a full-blown panic.
In fact, the US spent 10 years trying to prosecute Gary. He was looking at 70 years in federal prison.
But what information did Gary find that could cause the US government to become so aggressive?
Aliens.
