Springfield to require training after nooses found

The nooses were found earlier this summer hanging at the city's water and electricity department. One of the nooses was found at the workstation of a black employee.

Nooses are often considered symbols of racial oppression, invoking images of racist lynchings.

Springfield Mayor Tim Davlin says he didn't think sensitivity training would be necessary in the year 2010, but he's learned more needs to be done.

Authorities are investigating if criminal charges will be filed against the three white employees who allegedly tied and hung the nooses.
