Richie Hawtin kind-of embarrassed about pushing a monitor into a fan

It was an "unexpected turn" when Richie Hawtin pushed a heavy thing into a fan's face:

"Regarding the incident at Time Warp in New York this weekend which is being posted and talked about on the web, I would like to apologise here to the girl involved
[...]
It was not my intention that the speaker fell. Only to nudge the monitors in her direction and for her to understand that perhaps she had filmed enough. I was as surprised as I'm sure she was when it moved the way it did and the top speaker fell off of the stack. For that, I'm extremely sorry and embarrassed about what happened. This was never my intention. Sometimes being in the middle of the spotlight, continual cameras and glaring iPhone lights, things can get stressful and frustrating. I”m sorry that this frustration took an unexpected turn and took away from anyone's experience of Time Warp. I have tried to reach the girl to apologise personally but have not yet been able to track her down and will continue to try to contact her.”

It must be so frustrating to go onto a stage and discover that you've got a spotlight shining on you. Who wouldn't be surprised and confused under those circumstances?
