No you can't. Remember Trump's so-called "Muslim Travel Ban"? There were actually two Executive Orders that he issued. After the first, the EO was enjoined by the court within five days. The second was enjoined by the court in eight days.

And as we learned, democrats are way better at this than Repuiblicans are.

Come on. You don't seriously believe that the egregious BS gun control stuff that states like California and Washington pass was done with an earnest look at the Second Amendment in mind and in light of recent Supreme Court decisions, do you?

I'll answer for you: they know damn well what they're passing is BS but they pass it anyway because they know it'll take years to work through the courts.

You can't "buy time" this way. Again, it takes years.

Oh, boy:
Considering that both of the major terrorist attacks in the U.S. (the WTC bombing an 9/11) happened under Scenario A, that seems far more likely for someone that was trying to enter the country for the purposes of committing a terrorist act.

And what's happened since then? We've cranked up airport and travel security big time.
But what haven't we cranked up? Border security.

You're thinking about this like a lawyer who's hands are tied by the rules. The real world doesn't work that way. At all.
Team Biden needs to start getting creative and artful with respect to the administrative rulemaking they employ.

Here's a very, very simple one:
No one is permitted to have an asylum claim entered into the system until they've had a blood test performed.

Did any of them claim asylum? Again, if you're a terrorist who wants to enter the country illegally, your best bet is to try to do it without being caught - and then if you're caught, to just accept deportation and try again. Formally applying for asylum and sitting down for additional background checks and interviews is beyond foolhardy.

Wrong.
When someone walks over the border with no ID, then what? They get a quick interview, maybe their picture is taken and maybe they swab some DNA. If somebody coming over the border ISN'T in a US database that step is useless.

Meanwhile under the current system the prospective terrorist is over the line and is officially in the system...and in the wind.
