> People already risk death to cross the border

At what percentage would you say? 1%, 3%, 87%?

Does the country they are fleeing have no culpability? Why are they leaving?

Crossing the border illegally (for now) is a civil misdemeanor and seeking asylum is legal under US and international law.

> Does the country they are fleeing have no culpability?

The US definitely has some culpability for making other places harder to live in.

> Why are they leaving?

They're not doing it just for funsies.

A man runs out of a burning building. You shoot him. Dang, that building really should have had more culpability.

> At what percentage would you say?

Why do you ask? If it was the lowest figure you mentioned, or halfway between the lowest and highest, would one of those make it better?

Is the argument that this new tech will only kill n people on top of those that already die, so whether we fry less than 1% or a far higher figure, that one of those is better?

Focusing on the specific death rate doesn't change that crossing the border is risky, and some people will take their chances with or without the heat ray. It's one more variable in the calculation.
