It's a little easier to build a wall around the Eiffel Tower than along a 2,000 mile border. Would an extended wall have kept her killer out of the U.S.? Do you not think that illegal immigrants can defeat a wall or go around it? A $15B wall extension would be an experiment that may or may not work. When will Mexico start paying back the U.S. taxpayers that will pay for the wall extension? What is this open border that you speak of? Why would you say that people and contraband are coming into the U.S. unimpeded? Life is not without risk.
First of all, Trump is talking about far more security than just a wall. John Kelly describes it as a multi-layered approach. Use walls where they are necessary and not where they aren't needed (terrain often is a impenetrable wall). Then additional layers of border agents, electronic surveillance and even drones.
Our border is the single greatest crossing for illegal drugs countries into this country. San Diego alone is the single largest point of entry for Mexican Meth. We have 11M illegal aliens or more in this country. Clearly, the border is pretty open especially with Obama's catch and release.
So, unimpeded may not be quite the right word, how about quite open? And very callous of you to say life is not without risk. Go tell the families that have lost loved ones to illegal immigrants and say that life is full of risks. I would love to see you have the guts to take that action. Somehow, I don't think you do.
Trump's job is to protect the American people. As Obama said about gun control, even if only one life is saved, it is worth it.
Is the border any different than that single life to which Obama referred?
