Even ICE apparently knows this is cruel and traumatizing especially towards innocent children. According to
this woman they have specific policies in place to prevent or minimize the damage to children and families when they conduct workplace raids (apologies, I don't have the time or energy to locate the policies themselves). They just didn't follow them.
It's not hard to connect the dots and reach a justifiable conclusion as to why ICE agents don't feel obligated to follow their own policies regarding cruelty towards immigrant families these days.
