In series or parallel, the only redundancy you will get is when the outlets are open since BOTH switches will need to be in the open position for the circuit to truly be open. Thus, if one switch is still closed, the circuit will still be closed until both switches are in the open position. Closed will only require one of the 2 switches to close the circuit.
