Here is news for Hillary and Trump supporters alike. We have Physical Barriers. Some of them walls, good high walls like Trump wants to build, like what they have in San Diego. And they work very well, except for the fact they tunnel under them or people come through the border legaly and over stay their VISA. Other areas of the border it is geographically impossible to put up a wall, much less an effective fence. In those areas, mothers nature is the only deterrent, but skeletons in the desert and cayons show people still risk death. Trump can replace fenced areas with walls, but it will have little effect.
I see. It is futile, so just give up. Yes, things now are "too hard" in the new America. The diverse multicultural America, at one with the world.
The woman shot to death in San Francisco, and her family, should rejoice for our new diversity and tolerance.
Go Hillary. Go "open borders" Johnson. Money previously earmarked for border control, can instead be used to feed, house and educate the world, if they want to come here.
Sing Hallelujah !! Kumbaya !! You no longer need to place bills and coins in the church offering plate, for our government will take it for you, and spend it in ever growing amounts on caring for the world.
And if you object or complain, you are a racist and a bigot.
