A lot of people in that 5% take a plea for a crime they didn't commit because the plea is so sweet it saves them from trial on all of the charges, some of which they clearly did commit and might receive a higher sentence for than the plea deal. The overcharging is a trick by the prosecution to secure the plea. I see people charged with murder who plead to manslaughter when the case was manslaughter from the beginning, but who risks going to trial and being found guilty of murder? Minimum on murder is usually 20 years straight, whereas manslaughter is usually probationable.
