Subtleties of causality violation in black hole complementarity

We will start with a brief overview of Birkhoff's theorem with an intuitive explanation why there are no time dependent solutions for spherically symmetric Einstein's field equation in vacuum. This theorem will help us analyze the collapse of a shell of dust on a neutron star and highlight some resulting issues with Black Hole Complenentarity (BHC).
A simple thought experiment shows that BHC violates causality. While this violation is rather subtle and limited in scope, it can nevertheless lead to otherwise impossible consequences.
