Please show me the statistics where illegals are causing all the crime and or making this country unsafe, and don't just quote Fox News please. Also if you build a wall (and there is some built already) they will just dig under it. Build it 10 or 25 or 100 feet below ground they will just dig a little deeper. All republican presidents in my lifetime have needed fear of something to stay in power. Nixon had Vietnam, Reagan had ussr/cold war, Bush 2 had 911 and Trump came in with the fear of the awful vegetable pickers! A physical wall is wasteful and in that right very republican. A better smart wall is a great idea. There is no logic to thinking criminals are all coming here when the corrupt countries they are currently in offer much better opportunities than the US.
