I don't understand the article.

Suppose they had an algorithm for computing a risk score. Ok, so someone is determined to have a "high risk score". That doesn't mean that they've done anything wrong; at most, it means prioritizing them for closer scrutiny. That could still be discriminatory (e.g. focus on Turkish/Moroccan immigrants), but in itself - it's not supposed to lose anyone their benefits.

Also, the article says:

> Citizens had no way of ... defending themselves.

Why could they not sue the tax authorities in court, asking the court to order the tax authorities to withdraw their payment demands? If there was no evidence of them having evaded taxes, I mean.
