Clinton will have a statement on this I'm sure. She was starting a little early when she said the workers were let back in Ground Zero too soon.
It would have been funny to watch her and the enviro thugs standing at the yellow tape line saying you can't go in till we say it's OK. I can just see the space suits people wandering around with air samplers for 5 years watching the WTC smoldering. NYC would have gone under and the nation would still be under waiting for the air to clear.
It's possible that too much caution was used in the recent mine explosion and it costs lives. I'm all for safety, but when lives are at stake, there is almost always hero's willing to push the envelope to save lives. I don't think you can order someone in to harm's way, but it's been my experience there are always volunteers. Remember Columbine? Standing around when children are being murdered isn't good. At the very least the teacher could have been saved by a quicker response.
