I have a friend whose parents were just (incorrectly) detained by ICE, and had to pay a $3000 administrative fee to be released.

That _is_ the extremism. It's here.

Sure, that's extremism. That has nothing to do with ICE using software to identify illegal migrants. The argument in the article was not that the software often gets it wrong, but that -- even if it were right -- something would be wrong with it.
