Wow! If that's not profiling based on point of origin I don't know what is. Apparently only people from Central and South America have good intentions.
I'm not sure if you can't comprehend what I wrote, of if you're just being snarky, but I'll assume for the sake of argument that you really don't understand how people come into our country.
DHS's Secure Flight system flags people who are considered security risks when they book airline flights. Some of those might be subjected to additional screening, and others are denied boarding altogether. If a foreign national is a bad guy, Secure Flight will prevent him from flying into the USA...but there is nothing to prevent him from flying to Brazil, or Argentina, or Mexico, or Columbia, or Chile, etc., and making his way north until he gets to our southern border. That's not profiling...but I think you know that.

So how many have entered the U.S illegally in the last 3yrs alone? Tack on to that how many have entered illegally in the past several decades (your words). No one has suggested that MOST of them are here with ill intent. You also either can't or wont quantify what the word MANY equates to but to you it is apparently an insignificant number of the tens of millions that have come here illegally. Try explaining that to those that lost loved ones to rape, robbery and murder.
I'm not sure what point you think you're making about crime and illegal immigrants, but we needn't debate what "many" means...there are clear facts and figures available. Cut and paste the phrase "rate of crime for native born Americans versus illegal immigrants" into Google and you'll find a large number of reports and documents, from a wide variety of sources, indicating that immigrants who come here illegally commit crimes at a lower rate than native-born Americans. Here's one of many:

In your initial post on this thread you wrote: "Thousands of military aged men and boys have crossed our Southern border. No one knows for sure what their true intentions are. We foolishly release them on their own recognizance to disappear to only God knows where. Something bad is going to happen on a major scale. It's just a matter of time and time is on their side." Your xenophobic innuendo and fear mongering notwithstanding, I think the evidence shows pretty clearly that their "true intentions" are simply to work and earn money. Do some of them commit crimes while here? Yes. But the facts indicate that on the whole, they obey the law.
I say bring back interment camps on the level of those used during WWII. If you don't have relatives or means to support yourself you aren't released. If you are suspicious under any circumstances you will be deported. The whole idea of "catch and release" is what is causing most of our problems.
Nobody should enter the USA illegally...period. Our borders should be 100% secure...period. But if you Google the phrase "percentage of US population here illegally" you'll find the figures 11,000,000 and 3% of the total US population coming up in a number of documents.
That's a lot of human beings to put into internment camps. How and where would you house them? Feed them? Provide medical care for them? The idea is unworkable, and nobody in a serious policy-making position supports it.
It's time for all sides of the political aisle to stop their partisan bickering and posturing, and work together for the good of our country to secure the border and address this issue.
