Comment on "Protective measurements and Bohm's trajectories" by   Y.Aharonov, B.G.Englert, and M.O.Scully
  In the above paper [1], it is claimed that Bohm's mechanics can be challenged by a simple gedanken experiment involving a protecting measurement. Here we show that this gedanken experiment can be justified without problem and without contradicting the axiom attributing a physical meaning to the Bohmian trajectorie
