" Common law courts are only an important aspect of the Patriot movement. These vigilante courts use many tactics to make their presence known and to attempt to disrupt the traditional legal system. These tactics are collectively known as "paper terrorism." Typically, common law court members issue judgments against people and file liens against property in an attempt to enforce the judgments. Sometimes, these bogus liens are little more than a nuisance. Other times, the liens wreak havoc on their victims by clouding title to property, and it is often expensive to have these bogus liens removed. Members of the Patriot movement also set up shadow governments with their own officers and officials as a form of revolt against the federal government. For example, the freemen of Montana formed "Justus Township" and appointed their own "public" officials. Patriots who attempt to print their own currency and pass bogus checks feel that their own government is legitimate and that they can back their currency by their own faith and credit in the same manner as does the United States government.
