Susan,hi! I believe it would have been vidvic who told you the location of the panic button.I think hartley may have mentioned its location long before vidvic joined the forum.I don't dispute that there is a "button",but unfortunately vidvic can not either know or prove that that the button was indeed a panic button or that it was in situ prior to the murders as he did not know the Bamber family. As rightly pointed out by Caroline,if there was indeed a "panic button" installed at whf pre-murders and it was "active",much would have been made of this at trial,especially the "story" that Jeremy had allegedly set it off in order to test police response times.The prosecution would have had a field day with that!
