What it found, according to an 18-page search warrant application and affidavit, led to weekend raids on two Minneapolis homes and a temporary St. Paul office for the self-described anarchist group.

According to the document, investigation learned:

The self-described anarchist group — whose main goal was to “crash” the Republican National Convention,” according to its Web site — traveled to or communicated with affinity groups in 67 cities to recruit members and raise money.

Group members discussed the possibility of kidnapping delegates, blockading bridges, using liquid sprayers filled with urine or chemicals on police and throwing marbles to trip police and their horses.

At an “action camp” held from July 31 to Aug. 3 in Lake Geneva, Minn., one member talked of concealing inside giant puppets “materials” that could be used on the street. Others discussed the need for Molotov cocktails, paint, caltrops (devices used to puncture tires), bricks and lockboxes for protesters to lock themselves together.
