:We are "not" alone in being concerned I assume you meant ).  I'm glad to hear it and I apologize for not reading your input to the conversation more closely in that case.  I'm quite dismayed by the answers I'm hearing.  They suggest that something is not fully thought out.  Either that something is the manner in which they actually deal with these safety issues or it's the line of argument that at least one of the arbs has chosen to take to explain away a situation that doesn't look good.  Either way there are some serious holes in Roger's explanation and I think it would be beneficial to get to the bottom of them.
