How much experience do you have in identifying forged documents?
I'm against illegal immigration as well. I'm also for actual solutions that can work in the real world. A wall or fence works. CBP data proves that.
A multi pronged approach must be adopted.
First layer of defense is a wall/fence.
2nd layer, jobs. Mandatory jail and forfeiture of personal assets to pay for fines, for employers and employees who knowingly hire illegal aliens.
3rd layer, immediate and mandatory deportation of any illegal caught in the United States.
4th layer, punitive monetary penalties against sanctuary cities/states.
I don't have any experience in identifying forged documents but certainly there are those who do have it, like some FBI agents, for example. Like I said, with the right manpower (people could be hired and trained to identify these forgeries, like some FBI agents are trained to do), this problem could be drastically reduced.
I basically agree with almost everything that you said above, except for the order of your layers. Like I said, I'd place a wall last, not first. I think the wall is the least efficient part of this multi-pronged approach that I do favor. Like I said, I have nothing against a limited used of physical barriers in chosen problematic areas, which as a matter of fact, is already done, and has already been funded by Congress.
Trump's approach, which is one of merely insisting in building a "beautiful wall" across the entire border, is stupid, hugely expensive, and is a poor use of taxpayer's money. By the way, his mantra was that Mexico would pay for it, right? Just this part shows to you how stupid his idea is.
This said, I don't think that Trump is a stupid man. Much the opposite, he has many talents. One of them, is how he identifies issues that his base cares about and how he picks words and phrases that they gobble up. His idea of a "beautiful wall" is, like someone has mentioned here, a shiny political object that fires up his base. This, the wall indeed is. What the wall isn't, is an efficient solution to curb illegal immigration, or at the very least, not the most efficient one, as clearly demonstrated by the fact that there is no wall along the Northern border and there is no significant illegal alien infiltration of the Northern border. Canadians don't come here illegally because they don't need our jobs. Mexicans and Central Americans do, because they need our jobs. It's not the wall, my friend. It's the jobs.
Trump who is not stupid, most likely knows that (given that his organization is one that has extensively hired illegal aliens), but instead of focusing on this (which would damage his personal interests and those of his buddies), he focuses on the wall.
I love your second and fourth layers. They are absolutely necessary, and a priority, in my opinion. About your third layer, see below.
