Supporters of Anonymous, the loosely organized group of internet activists who have attacked the Church of Scientology recently with videos and server hacks, appeared outside D.C.’s Founding Church of Scientology center on Sunday. The protest was part of a planned “global day of action” with the stated purpose of setting off a government investigation into how Scientology got tax-exempt status.

The Feb. 10 protests, which took place in dozens of cities, were initially announced last month after a video attributed to Anonymous coincided with an online effort that managed to temporarily knock out servers belonging to the Church of Scientology. The date was chosen for the protest because Feb. 10 was the birthday of Lisa McPherson, who died of a pulmonary embolism in 1995 under the care of a branch of the Church of Scientology.
