SfPW,
If it is a lifesaving work, then they ought to start using more effective warning methods than door knocking. A few pointers could be taken from the emergency services around here, from the way in which the recent bushfires were handled:
i.e.
- Bushfire warnings firstly issued by radio and television broadcasts.
- Then the final evacuation orders issued from the loud hailers on the emergency service vehicles.
One can only be thankful that the emergency services didn't attempt to rely on door knocking to get bushfire victims out of the way of the flames!
Of course, if it is not after all a "lifesaving" work, then why bother at all?
Bill.
