New York City jailed protesters in violation of the Constitution

For more than two months in 2001, protesters in New York City who were arrested were jailed overnight instead of being given summonses, a violation of both the First Amendment right to free speech and the 14th Amendment right to due process. Those arrested were protesting the police killing of unarmed Guinean immigrant Amadou Diallo.

The plaintiffs also sought to show that in the two previous years, the city had an unwritten policy of locking up protesters, but the jury determined that such proof was not present in the plaintiffs' case.

The Giuliani years were filled with violations of citizens' civil rights. Something like 26 or 27 civil rights cases were filed against the mayor personally. He lost all of them.
