Fences are both a technical and a symbolic force when marshaled by those who seek to announce and defend their property interests. Fences are also seen as a constraint on the freedom of others to make use of public or collective resources. Although the ultimate status of a particular bit of fence was often determined through the use of deadly force (Anderson and Hill, 1975), the resolution of these conflicts at a more general level came to depend upon the establishment, interpretation, and enforcement of the rule of law (McFerrin and Wills, 2007).
