Wasn't David Tseng prevented from entering one of the California dates on the last tour? Don't remember much of a fuss that time around. He must be used to it by now, I would have thought. Fair play to the guy for carrying on in the face of adversity.
At the same time though, as an information provider/facilitator one has to accept some degree of responsibility for the fear and loathing that often seeps through around here. You can't just step back and say 'Oh that's the internet for ya' or 'All human life is here'. That argument is just a cop-out.
No I was not prevented. I got tickets to San Diego that happened to be pit and seeing how close it was I decided to move back. Security was looking at me when I was down there briefly but I was not thrown out. The seats I had in Copenhagen were in the balcony. I have never intended to cause a distraction or any problems.
