Trump's 2018 zero tolerance policy which separated immigrant children from their parents at the border with no plan for reuniting them shocked the conscience of many Americans. And even though Trump claimed to cease the practice within weeks, zero tolerance is rooted in American law that dates back 100 years and remains on the books today. It can easily happen again.
