Sometimes working in witness protection takes a lot of patience and time -- like "three years, five months and 16 days."

Watch the video after the jump. Sometimes working in witness protection takes a lot of patience and time -- like "three years, five months and 16 days." That's how long an agent on 'In Plain Sight' (Wed., 10PM ET on USA) has been in a coma, and the WITSEC team have been protecting him ever since, in hopes he'll wake up to give case-closing testimony.
