I hate that “eradicate them” sentiment I’ve seen in some places too. And I think Pavel’s initial comparison and implication of internment camps horrible.

I’ve tried to think of what increase security scrutiny would even be. A quick look at ICERD says, broadly, you can’t restrict movement, speech, or general participation in life.

I guess it depends on exactly how you interpret:

Each State Party shall take effective measures to review governmental, national and local policies, and to amend, rescind or nullify any laws and regulations which have the effect of creating or perpetuating racial discrimination wherever it exists;

I don’t think increased investigate scrutiny would be restricted here. This might include things such as increased time spent verifying visa application or other governmental procedures. I could also see investigative resources spent on criminal cases.

Those are things governments typically have very broad discretion with. But I’m not a lawyer maybe there’s something else.
