At the shows that I heard of where there was an issue with photos being taken, security dealt with it for the most part. I myself almost got booted for taking pics at the Stevie/Don show in Pittsburgh, due to the fact that when I left for the show, the website stated pictures were OK. When I got there, I took my camera in without a problem. Halfway through the show, 1 security guard stopped me, another said it was fine.
I never use a flash, and I highly doubt Stevie was distracted by me in the 5th row far right - she certainly wasn't bothered at last summer's Camden show when pics were permitted & I was right at her feet snapping away.
However, if she had asked security to stop people from taking pics, or if she said "please no more pics" I would have stopped. If I didn't, I would have nothing to bitch about when I got tossed out. I get much more upset at people yelling things out in the middle of songs, or drunkenly spilling drinks on others, or hitting others to get up front for Edge rush, or talking on the phone not watching the show while they're sitting in the front row than I do at people quietly taking pics or simply holding their phone up so friends at home can hear a song.
I know what you're saying, Strand, and again, I agree that what Tori did was unprofessional. Could she have done it differently? Sure. BUT I totally understand why she blew up like that. I do NOT think this was diva behavior, I think it was her scolding people for not appreciating the show & being disrespectful to other fans around them. Just like the Manchester(?) Mac show that someone brought up earlier in this thread - physical altercations during a performance? WTF? Were Stevie & Lindsey unprofessional for yelling at those people to get out? Maybe, but it wasn't uncalled for either.
