I've never seen anyone get seriously hurt during the frenzied worship stuff before, although have seen people get bumped into quite a few times. I imagine the church's insurance would be held responsible since it would be considered an injury on church grounds?
It seems ridiculous that our "worship" would be so out of control that it causes physical harm to people. I don't see how that glorifies God at all. People need to be careful.
I do remember years back at Youth Camp the counselors had to keep an eye on the boys that were "slain in the spirit" at the altar calls to make sure they weren't looking up the girls' dresses...I guess they actually caught some doing that.
