For years, the FBI has threatened brown people with a miserable existence unless they're willing to become informants. What should be illegal somehow isn't -- or at least hasn't generated enough courtroom precedent to force the FBI to knock it off.

The FBI routinely approaches Muslims and people traveling to and from countries the US government considers questionable and tries to intimidate them into ratting out their friends, family members, and colleagues. Whether or not there's actually any ratting out to do seems to be, at best, a secondary concern. The FBI has spent years using informants to radicalize people, which it then arrests the moment they become radicalized enough. The FBI's counterterrorism budget depends on a healthy stable of informants and so the pressure tactics continue unabated.
