We use the Julia-Toulouse approach for condensation of defects to show that
the topological Abelian BF term can be induced due to a condensation of
electric charges and discuss how to include external magnetic defects into the
Maxwell-BF theory in a way consistent with the Elitzur's theorem. We also
discuss a new way of obtaining the Dirac's veto, which is based on the
so-called (Dirac) brane symmetry.
