FBI Visits in Seattle Prior to May Day

IGD (April 30, 2018) reported in A Note on Recent FBI Visits in Seattle that "FBI agents visited at least three houses in Seattle and left business cards with the names of individuals they wanted to talk to written on the back. These visits have become a yearly ritual. In the week before May Day, the feds do the rounds to make sure that everyone knows they are watching." The article was originally posted by Puget Sound Anarchists.

May Day in Seattle has frequently been the scene of violence and targeted property damage. The FBI Joint Terrorism Task Force (JTTF) likely seeks contact with known activists and anarchists in the Seattle area in order to develop information and sources.
Local anarchist groups have claimed for years that the FBI, state fusion centers, and even the local military is spying on them and denying their Constitutional rights; as can be seen in this article in The Seattle Globalist (July 25, 2014). 

Anarchists groups in turn target law enforcement, military, and government employees in campaigns of information collection and harassment. A circle of events that repeats itself each year on May 1st, in Seattle and other cities around the world.

Violent action will always trigger a police response, and planned violent protests that occur year after year will almost certainly result in known activists and anarchist being the focus of government surveillance and intelligence collection.
