People had been afraid to speak out. They fear repercussions; they fear being targeted, because (the Border Patrol) is so dominant and so imposing in their communities, where they're told they don't have any rights.
They just keep throwing money at the border with all these new novelty things that they try. It's just a waste of taxpayers' money.
It's an incredibly costly endeavor, and then on top of that, walls don't work. All the fencing has done for the last 10 years is to push people into crossing the border in more and more difficult and dangerous terrain.
