Sympathy for McCanns must be tempered

How kind Colette Douglas Home is to Gerry and Kate McCann (Comment, July 22). She uses many column inches pouring scorn on the Portuguese police (perhaps justifiably, I don't know), showering Gerry and Kate with sympathy (I, too, feel for them), but only makes passing reference to the action that, had it not happened, would have prevented this heartbreaking event from occurring in the first place.
