Tasky, I know I say this to you alot, but what the f___ are you talking about, man?
The US-MEX border is an economic engine of illegal activity... Lives depend on these cartels being able to get their product to market... You really think a little bit of concrete and rebar is going to stop that?
I wouldn't be surprised if some of the contractors building the wall are bankrolled by the cartel.... Put 1/4 of that 8 Billion towards surveillance, detection, and enforcement and you'd have a far better bead on slowing down the traffickers.
