FBI issues alert that cops may be attacked by anarchists on Halloween

The Federal Bureau of Investigation is warning police departments in twenty cities that cops may be attacked on Halloween. One of those cities is Detroit, which is no stranger to Halloween-related mayhem.

From ABC 7 Detroit:

The Grim Creepers are proposing the Halloween revolt. They're part of an extremist group known by feds as the National Liberation Militia.

Detroit Police Assistant Chief Steve Dolunt acknowledges the serious nature of the threat. He learned the group has encouraged members to wear Halloween masks and create a disturbance to lure in officers and then to use weapons on them - weapons such as bricks, bottles and firearms.

Yes, cop lives matter.
