Exactly.. Trump is promoting the idea that immigrants are walking across the desert where there are no roads to get into the US or smuggle drugs.
More technology AND severe penalties for employers (like Trump) who hire illegal immigrants. Wouldn't hurt to beef up E-Verify too.
Yet no mention of the illegals that come over without permission. Interesting that you don't want to punish them.
When those illegals are found, put them in similar type housing as FDR did to citizens of the U.S. with Japanese heritage. Feed them tainted food and let them drink water from Flint, MI. That should solve the problem quickly.
