That's actually the nature of bayesian probability: if something is happening a higher proportion of the time vs. before, it's more likely to happen now vs. before. If that something is bad, that means higher risk. It's expected that a rational actor would act to minimize risk to them.

Precisely how rare is it, over the last couple months, for US immigration officials to detain someone (perhaps "for further questioning", perhaps to a prison) who hasn't violated any laws? Claiming "it's rare" isn't very useful. Remember, the expected probability is ~0.
