Fliers attacking Jews and blacks were sent to more than 25 police departments in Westchester just days after the county offered a training session to help police identify and track hate groups.

District Attorney Jeanine Pirro Wednesday that her Bias Crimes Unit was investigating, but added that because the material did not urge violence, mailing it to police was not a crime.

“This is a package that obviously spews hate and one that is very disconcerting,” she said.

The fliers, culled from the Internet, included pages titled “Jew Watch,” attacking the Anti-Defamation League, and a call for white men and women to join the Ku Klux Klan. The return address on the manila envelops listed only Concerned Citizen of Westchester and indicated it was from Yonkers.

Lovely.
