A direct very simple proof that there can be no closed trapped surfaces (ergono black hole regions) in spacetimes with all curvature scalar invariantsvanishing is given. Explicit examples of the recently introduced ``dynamicalhorizons'' which nevertheless do not enclose any trapped region are presentedtoo.Comment: 6 pages, no figure
