This is actually a fairly accurate video (and it seems that it is worst than when i was there 15 years ago somehow, the ditch and the morrocan side fences are new). I don't like that some opinion were leaking through the depiction of facts (even if i have the same opinion) though, but i understand this is hard.

You can see this not a wall (because you can't see through walls obviously), and that this is not effective without border security agent. Do you know that even with a see-through fence and cncrete floor, people were still able to dig themselves in? They though about creating an artificial underground river alongside a the time (it is probably replaced by the ditch now).

They hired a team of engineer in the late 90s (or early 20s at least) to create a secure door system that won't force people from morocco who work there to wait unknown amount of time. If maquiladoras are still a thing, you might have to do the same.

I don't think a wall is a good idea, but maybe US should try it. Please be accurate though, if you want to have an efficient border "wall", it should never be a wall, but a fence, and you should actually have border agent monitoring the fence at all time.

Also thank you for the video, i'll binge watch this tonight.
