...20 years in prison, then out before 2 years...
I think the system does this to criminals who belong to some politically correct protected category. When the crime is too heinous to merely let the criminal go with a suspended sentence, they will give her/him what may look like an appropriate sentence but then when the story is out of the public eye, the system works to let the criminal get out after a short term. It is all part of the political system’s art of manipulating the public. They spend most of the time lying to us rather than doing what they are supposed to.
Well, the mother is white and ugly - maybe that is a protected class.
