No its not reasonable to criticise someone when the full facts are not known. After the inquest if the layout is blamed then yes but not before.

The coroner in Svetlana Tereschenko's death made it explicitly clear that Boris has questions to answer:

A coroner recently described elements of the pre-existing CS2 route as "confusing" and "an accident waiting to happen" following inquests in to the deaths of Brian Dorling and Phillippine De Gerin-Ricard. With the previous death of Svetlana Tereschenko, and last week Brian Holt, four London cyclists have died on or near CS2 since it was opened in July 2011.
