We show that for translation invariant Markov random fields: (1) the K
-property implies a trivial full tail; (2) the Bernoulli property impl
ies Folner independence. The existence of bilaterally deterministic Be
rnoulli shifts tells us that neither result is true without the Markov
assumption (even in one dimension). We also show that for general tra
nslation invariant random fields: (3) Folner independence implies a tr
ivial full tail.
