Your "data" is not very convincing. Illegal immigration is the lowest in 15 years. Great data point. But this data point does not lead to the conclusion there is not a national emergency with the present amount of illegal immigration.
Ahh, this is something we can work with. I will rely on your claimed experience in the sciences for the next bit.
I earlier posed this but you appear to have ignored it, so I'll go over it again. When testing something like this I am testing whether I should give DJT his money or not. Do I feel he is lying to get the money or is it a reasonable ask. (Bear with me, obviously I'm speaking generally).
DJT predicates his claims on the presence of an Emergency. You correctly note that not all emergencies are time-sensitive, so we can't simply assume that because Trump didn't shut the government down during the first 2 years of his administration over this "emergency" to say likely he is lying. But here's how I construct the hypotheses:
(I am counting on you remembering your days doing inferential statistics when you were a sociologist).
Ho (Null Hypothesis): There is no crisis (no need for an emergency declaration)
Ha (ALternate Hypothesis): There is a crisis (need for an emergency declaration)
Note how I constructed that. Just like your sociology experiments or my chemical experiments we first set up the null as "No effect" and
test against that. The goal being to see if we can REJECT THE NULL without making an error or FAIL TO REJECT THE NULL.
Now, obviously, we are not working with quantifiable data here so we are left with some more abstract measure of the data.
Is there a crisis or need for an emergency status? Here's the data that I'm using:
1. Illegal immigration numbers across the southern border are DOWN over the past many, many years.
2. Most illegal immigration comes from people overstaying visas (meaning it isn't illegal crossing of the border, especially not along the southern border)
3. Trump promised the wall during his campaign and he made the promise very specific including the size, shape, materials and the fact that Mexico would pay for it. He did this repeatedly.
4. Trump had 2 years to enact this emergency measure to build the wall. But he didn't. Instead he focused on giving tax breaks to millionaires. Suddenly when his party is no longer in power the "Crisis" shows up.
5. The wall is now very different. It isn't a concrete wall, it is steel slats. And most damning of all is that Mexico is clearly NOT going to pay for the wall, by any means whatsoever.
6. Trump and his spokespeople lied about the scope of caravans, especially closer to the election time.
Right now there is almost NO DATA WHATSOEVER that justifies that we decree an emergency, certainly none that is any more pressing today than it was 2 years ago when nothing was done about it by Trump.
Remember: in order to justify the claim of a crisis or need of emergency response there must be actual data in support of that claim. It is not incumbent on anyone to show evidence that there IS NO CRISIS. That is called proving a negative.
And that isn't how we assess this. Look back the model. I'm testing against the null. If there's no data in support of rejecting the null I would be in error to reject the null. That would be a Type I error (false positive)
So let's go one step further. Why would I be hearing that there IS a crisis when no data really support the contention? Well this is where it becomes interesting to look at the source of the information. When I run an experiment in the lab and I keep getting data but I realize my equipment is grossly malfunctioning I cannot then just throw up my hands and say the data is what it is. I have to make sure my equipment is measuring what I think it measures.
Trump lies. He has lied consistently about the Southern border. Whether its lies about the number of "terrorists" detained at the border, or it's lies about diseases coming across the border, or it's likes about the crime rate due to illegal immigrants or it's lies about who is in the caravans, or the amount of drugs coming across the southern border etc. I have a very hard time finding ANYTHING that Trump has ever said about the Southern Border that is true. Ever. Seriously. Can you show me something?
On top of that Trump lies about everything no matter how unimportant.
If I had a piece of lab equipment that almost NEVER GAVE THE RIGHT RESPONSE TO A STANDARD I would be making a serious error in using that data in support of my analyses.
Now, lest you think I'm the Speak or the House or Vladimir Putin or someone with power over the President I want to calm you a bit and let you know I'm just a person. I'm trying to figure out if the claims being made to me are likely true or likely false.
This is how I'm approaching it. I'm doing it using the same tools we all use in the sciences. Best estimates. Best fit of the model.
Hope that clarifies it a bit. Maybe you can dial back the personal attacks and read what I wrote.
