Worldwide Caution

U.S. Department of State guidance for a worldwide caution.

Funny, everyone outside of the US should exercise increased caution when dealing with or visiting the US.
Or better yet: don't visit the USA at all.
Indeed, particularly given that ICE agents are going to be deployed to airports. Their penchant for killing civilians and otherwise violating civil rights only to lie about their actions hardly seems like a good fit for airport security duties they haven’t been trained to perform.

> duties they haven't been trained to perform

Which implies they've been trained?
