In this paper we first discuss the analysis regarding the role of Lorentz symmetry in the perturbative non-gravitational anomalies for a family of fermions, which has been recently perfomed in arXiv: 0809.0184. The theory is assumed to be translational invariant, power-counting renormalizable and based on a local action, but is allowed to have genera Lorentz violating operators, including those that break CPT. The main result is that Lorentz symmetry does not participate in the clash of symmetries that leads to the anomalies. Moreover, here we provide a simple semiclassical argument that shortly illustrates the origin of this fact.
