I don’t blame some of them...but even the ones with good intentions who don’t follow the rules abiut how and when to enter the country should be invited to leave. The point of the weaponry is to dissuade anyone from trying to enter in any way but at an approved border crossing, and to make sure that the coyotes, drug gangs and terrorists masquerading as immigrants understand that there is a line that we won’t let them cross.
I guess the point that I was trying to make is that if there was no financial benefit for illegal immigration, you would see a lot less of it. A lack of jobs for the undocumented would be a virtual wall that would be far more effective than weaponry.
