The march coincided with Guy Fawkes Day, commemorating the 408th anniversary of a failed assassination attempt on King James I by a group led by Fawkes. At public events, Anonymous participants usually wear Guy Fawkes masks, popularized in the movie "V for Vendetta."

A 1988 state law makes it illegal to wear masks that conceal one's face while on state property, punishable by fines of up to $500 and/or up to one year in jail.

Anonymous listed two other protest locations in West Virginia, in Martinsburg and Morgantown.
