Most people in America are not murderers and rapists, but some are. Some people trying to enter the US are murderers and rapists. A wall would make it more difficult for rapists and murderers to enter the country undocumented. If they enter documented, then we know about them, and can solve future rapes and murders easier.
I agree about the murderers and rapists, etc.
Just look back at what happened when that fool, Carter - the very epitome of the very worst in too Liberal of a view, if there ever was one fool of a representative of that - when he because of that, allowed himself to be hoodwinked by his Kim Jung Un, back then, and next thing the U.S. knew, all sorts of criminals of the worst kind released by Castro from his prisons, ended up in various parts of the U.S. commiting all sorts of crime.
At the same time, said Carter fiasco goes to show that "A Wall" will not solve such problems.
That as with death, crime and corruption are no respector, either of would be measures against them, nor of such a thing as a day off.
It is ever up to no good.
Ever up to the no good of somehow finding a means around what ever "wall" is put up, against it.
Which is one reason why our right to bear arms, is so important, a right.
That and the fact that just as what happened because of Carter's naive belief that a good deed will be respected in kind, eventually went the way of such things...went away, with the passing of time.
We're basically repeating one aspect or another, of the ups and downs and adjustments to same, of our long, glorious history as a country like no other on this Earth, to this very hour, once more...
