Gettysburg Pennsylvania authorities are on edge over rumors claiming the leftist group Antifa may cause problems at this weekend’s battle reenactment. According to Fox News, some fear the group may cause damage to gravestones and even burn a Confederate flag. While peaceful protests are legal, such action on Antifa’s part will not be tolerated. While the Central Pennsylvania Antifa group denies the rumors, United States park police are taking the reports seriously. The reenactment is highly attended, and authorities are preparing for any incidents that may arise.
