I agree totally with Winston regarding window safety locks removing an escape during a fire. Admittedly you probably would not want to jump from a multi-storey building to escape a fire but fire brigade access is also restricted especially in the incidence of lost keys. I too wonder where responsible parenting is represented. No child death is acceptable but given the number of children who live in multi-storey buildings, very few fall from windows…. Again one is too many but wondering how this will play out.
