Covering camera openings on your camera is up to you, it only affects
you, and who ever else has access to the camera.
However, covering a camera eye on a piece of property which does not
belong to you, may make you liable to an act of criminal damage, as you
are, with intention, preventing a company or person which owns the
property, offering a service to the community, as well as gathering
information from the surrounding environment, for its own purposes, and
perhaps that of the community, to which it is entitled. You could also
be privately sued for limiting the lawful exercise of a company to
gather information about its environs, especially if the camera is
licensed by the local authority...
So there...US Law might be different...but I doubt it, as Human Rights
and Civil Liberties are non events these days in US courts, national
security and private enterprise corporation law taking precedence over
individuals rights and liberties.
Food for thought,
