I live near the border and there used to be "border bandits" that came over, broke into a house at night, terrorized and tied up the residents, loaded everything they wanted in the victims pickup and drove back over the border. the wall they built about maybe 10 years ago stopped that, so i'm a big supporter of the wall and Trump.
One thing that bothers me though is Trump saying Honduras etc. should stop the caravan, and that they "can't control their people".
People should not be imprisoned in their countries, Mexico's constitution prohibits the Gov from preventing people from leaving and it's Mexico's responsibility to keep them out.
I've often wondered if the wall is ultimately going to be used to keep us all in, our constitution lacks a guaranteed freedom to leave.
