The scattering amplitude is explicitly written in terms of the commutator of the field operators far from the scatterer only, so that microscopic causality'' cannot be inferred from the scattering amplitude alone. It is shown how to construct a nonlocal Hamiltonian for a KleinGordon particle which gives exactly the same scattering at all angles and momenta as that from an arbitrary local scalar potential, but differs in that the commutatar of the field operators does not vanish everywhere outside the light cone.
