Edward Snowden a year on: Odyssey of the whistle-blower
A second look back at the events of one year ago details how Edward Snowden's exposé of secret US mass surveillance took him around the globe
"If I could go anywhere in the world, that place would be home." So said Edward Snowden in Moscow on May 28.
Home is, of course, America. But for the 30-year-old former NSA contractor, who turned his life upside down to expose the mass surveillance carried out in secret by the US government, the exact location of home is difficult to pinpoint.
Maryland - one of the wealthiest states - could stake a claim. It is where Snowden spent his formative years, attending primary and middle schools in Anne Arundel County, between Washington and Baltimore.
Snowden dropped out of high school in 1998 after a prolonged illness. As a result, he spent long periods at home.
It was during this time that his fascination for how things worked developed into a passion for computers and technology.
In 2001, when he was in his late teens, his parents divorced.
