Looking at the border issue can be done from two perspectives, one emotional and the other logically. Emotionally it tears up anyone to hear a child cry, to even imagine a child crying from need for its loved one and protector. From a logical point of view children separated from loved ones by military service, long business trips, or due to felonious activity by a parent caught by law enforcement also cry for their loved ones. Historically open borders have been a disaster for any country that allows it. That's why all countries do not allow it. Looking at any issue using only logic or only emotion never yields a quality solution, nor does it provide a productive platform for discourse.
