I will even take it a step further that it simply won't be effective for it's intended purpose. If you want to help the problem of illegal immigration. Fine, I am for it. But a $20bn dollar wall? For what, exactly?
*blinks*
Not sure that's the real question, given the obvious answer is "no" due to negative environmental and humanitarian impacts.
It's not so obvious when there's no published plan for the "wall" yet.
I put it in quotation marks because many people assume that it means a
continuous physical wall of massive proportions. Even Trump wouldn't
mean such a slavishly narrow definition. I expect the wall to be a combination
of a regular wall (which we already have in places), sensors, analytical systems,
patrols, & other such means as would be optimum.
I offer a money back guarantee on this prediction.
Problems will be.....
- Aerial countermeasures, eg, drones, ultralights
- Tunnels
- Volume of attacks
- Ramping up the border patrol labor force
- Wildlife habitat fragmentation
Drug legalization strikes me as a good option to defeat smuggling.
