Meg Barclay at the risk of prolonging this issue, there are two things that comes to mind. The first is:
We are so very, very jaded and so very suspicious of everything and every one we sadly spear no time for reflection. Best you erred on the side of caution than to have hung the innocent.

You would seem to have done both things so very well. Blame is not yours it is the very cautious humanity in your ways that is in fact the glue that keeps us together instead of breaking out into an uncontrollable mob of regret>
