Illegal Immigration

[Yonadav]

I'm sorry man but I think you're the one with the false belief about a wall being an easy obstacle.  I meant to link this in my previous post but it looks like I screwed it up somehow.  I fixed the link in the previous post too.  They've had prototypes built and they have all been very effective at preventing people from scaling, or even using tools to cut into the wall.  Also, most border partitions already in use are installed 6 feet deep as it is.  Yes, people can still tunnel under them but few and far between are going to do so.  Climbing is not easy and it's risky.  Think of just one of those rock climbing walls with the rubber grips and imagine it 30 ft high.  Would you climb that with no scaling equipment or safety equipment with little to no climbing experience?  Then imagine that it is just smooth concrete instead, nothing to grip onto.  You likely didn't bring a grappling hook and safety harness with you because a) most of these people are coming from poor countries with barely enough money to eat let alone buy recreational climbing equipment and b) climbing equipment is heavy so you decided not to trek through the desert with it.  Speaking of trekking through a desert, you're tired, thirsty, and overheated.  And if you have your family with you, you run the risk of being separated if some people can't make it over the wall.  It not a matter of someone having enough time to make the climb, it will literally be almost impossible to scale a wall of that height.

With the wall keeping most people out, you can then use surveillance more wisely in the areas without a wall and points of entry.  You are correct that surveillance can be done with less manpower, but the problem is surveillance doesn't actively prevent someone from entering the country illegally.  Manpower is required to detain illegal immigrants, we can't just use the video of someone illegally crossing and write them a ticket.  That's why having a wall that is near impossible to scale (which prototypes have shown is very possible), can be used in conjunction with surveillance at segments of the border without a wall to more effectively utilize the manpower we have.  This would make border security a lot tighter.

But the Maginot Line worked so well!
