I am no Trump fan but the wall may save a few souls
How on earth is a wall going to prevent drugs coming in? You think the drug lords are gonna go bust cos of some brinks and mortar? "Oh well, he's built a wall ... let's shut down now".
They will find ways with or without a wall, I read a statistic that a large percentage of most movement into the US is actually underground.
Apologies to hijack the thread.
