Consider a locally compact second countable topological
transformation group acting measurably on an arbitrary space. We show that the
distributions of two random elements X and $X'$ in this space agree on
invariant sets if and only if there is a random transformation $\Gamma$ such
that $\Gamma X$ has the same distribution as $X'$. Applying this to random
fields in d dimensions under site shifts, we show further that these
equivalent claims are also equivalent to site-average total variation
convergence. This convergence result extends to amenable groups.
