BFT,
I got your pm and here's my thoughts.
Don't in anyway try to tape Pearl Jam the rest of this tour. I know as a taper it is tough to take a night off. I get offended when anyone asks me to take a night off. But IMO, if you do risk taping another show while this security personnel is looking for you and you get busted again, it will leave a huge negative impact on anyone else that tries to tape Pearl Jam in the future. Much like the way I do not support video tapers and IEM tapers of audio-friendly bands that just bring bad attention to the people that are playing by the rules.
I know it's tempting to try to beat this asshole, but just let him win this one for the sake of the rest of the tapers.
Because all the dates are in big markets (since they shut out everything south of DC), I'm sure high quality audience tapes are being made at most of the shows esp SF.
I'm not sure if I would confront this guy about it either and show him up with PJ's lame taping policy. It just gives him more reason to remember you if he's still doing this on the next tour.
