You're attempting to do what Obama did -- play into the bleeding heart via appeal to the victim-mentality mindset .. void of relevant facts.
Thus you've made no rational cogent argument in support of your point.
You're simply emotionalizing, and that prevents you from seeing the truth.
It's not about the U.S. criminal justice system.
It's about the parents, the illegal aliens who committed crimes knowing if they'd get caught what the penalties would be for them and how it would affect their children.
Your upset is simply misplaced.
