(CNN)St. Louis' and Philadelphia's police departments have launched investigations after a group linked racist and anti-Muslim Facebook posts to the accounts of current and former officers.
The Facebook posts include images of the Confederate flag, call for immigrants to speak English, criticize Islam, encourage violence and more.
The posts were compiled by The Plain View Project, which describes itself as a "database of public Facebook posts and comments made by current and former police officers from several jurisdictions across the United States."
The group combed through thousands of posts from officers in eight jurisdictions in the United States. CNN has reached out to all of the police departments.
