Except for the whole anchor baby situation which is not going to change. Except for people coming here to engage in crimes and sell drugs. The people we have to worry about most aren't the ones who want to be productive citizens, it's the ones who want to take advantage of the system. It isn't just a wall we need to erect, it's a whole system that stops them from crossing the border, period. Dead or alive.
I live 50 miles from the border; I am all for stopping the masses. Building a wall and arming it the way that you are suggesting will not happen. Dont pretend that we will ever put mines and have machine gunners manning vast stretches of desert. Your idea is complete fantasy. Even if Trump was elected he wont be able to do what you are suggesting, not unless ISIS moved into Mexico. But even then we are not going to put mines at the border. And we are not going to build a wall either. Not only would it cost tax payers too much money for false hope, it would take too long to be of any use. It is a very long ways from San Diego to Brownsville.
