Nov. 3 promises to be an Election Day unlike any other, and public safety entities say they're preparing for tensions and the possibility of violence.

Poll workers are usually the first line of defense in case of disputes between voters, though they may be backed up by private security guards. Some local election authorities say they'll be adding guards, and Washington state's King County says it will post guards to ballot drop boxes that in other years have been unattended.

As U.S. law enforcement departments are accused of racist policing, one of the most common responses by the people in charge has been to have officers take "implicit bias" training.

The training usually consists of a seminar in the psychological theory that unconscious stereotypes can lead people to make dangerous snap judgments. For instance, unconscious associations of African Americans with crime might make cops quicker to see them as suspects.
