[otrkid1970]

Just a few Days Ago 8-10 Military Helicopters Landing and Extracting Troops in Downtown Los Angeles.  I live in the Country Area of Massachusetts where there are Militias and other Groups. The Rumors have always been the Government is preparing For Marshall Law. For what reason Though? Why would The U.S. Be training against it's own citizens??  Here is the Video. The building the troops come out of is the Guatemalan House of culture on Wilshire Blvd.

In this Video they show troops detonating Flash Grenades inside and outside the Building.
