To give a tangible example, Aaron Swartz was offered a plea bargain for six months in federal prison, on charges that carry a maximum sentence of 35 years imprisonment. In simple game theoretic terms, it's usually optimal to take the plea bargain even if you're innocent, you've got good representation and your case is strong. A certainty of a short sentence is preferable to the possibility of your life being ruined.
