Gabe Watson has kept a low profile since he was set free on February 23 when a Birmingham, Alabama court ruled that there was not enough evidence to continue his trial, but he’s well aware that in the court of public opinion, many people  believes he is in fact guilty.

The 34-year old will tell his side of the story on Friday’s 20/20 on ABC., In the exclusive interview, Watson claims that he didn't know his late wife, Tina Thomas Watson, had never dived in open water before, despite having 11 dives under her belt.
