I once opted out at LAX T2 and the TSO still asked me to walk through the BKSX to get to the groping pen. I said, "Sorry, but I am not walking through that thing. I don't care whether it's turned off." He rolled his eyes and made it seem like I was disrupting their whole operation (i.e. challenging their authoriteh), but it really didn't take much effort for them to watch me walk around it.
