Illinois requires homeless sex offenders to report to law enforcement weekly, but those with fixed residences need report only quarterly. Tired of weekly updates from homeless people, some Chicago cops instruct them to list shelters as their fixed residences—knowing full well that the registrants don’t reliably live there. But a schism lurks! Other police officers dislike that approach and arrest homeless people who list fictitious residences. Caught in the bureaucratic crossfire, one such offender finds himself arrested and jailed for 17 months before being acquitted. And his due process claim is not barred by the statute of limitations, says the Seventh Circuit, so it can proceed.
