@Olivier5,
The difference trump made was he decided to enforce the laws at the border, treating those who crossed illegally as criminals. Our long-standing arrest procedure requires that children are placed in protective custody when their parents are arrested-if there’s no other family to give them to.
Obviously, in this particular situation, there’s no extended family on hand to take responsibility for the children.
So, trump’s decision to enforce prosecution of illegal immigration spiraled up the number of arrests, which spiraled up the number of family separations.
It’s not rocket science. I don’t understand why people act as though they can’t connect logical cause and effect.
